This array is supposed to have 10 elements. Smatch complains that with
the current code we can have n == max_ints and read beyond the end of
the array.

light, uv index and proximity sensors
The si114x supports x=1,2,3 IR LEDs for proximity sensing together with
visible and IR ambient light sensing (ALS).
Newer parts (si1132, si1145/6/7) can measure UV light and compute an UV
index
This was tested on si1143 and si1145

Pull char/misc driver fixes from Greg KH:
"Here are a number of small driver fixes for 4.8-rc5.
The largest thing here is deleting an obsolete driver,
drivers/misc/bh1780gli.c, as the functionality of it was replaced by
an iio driver a while ago.
The other fixes are things that have been reported, or reverts of
broken stuff (the binder change). All of these changes have been in
linux-next for a while with no reported issues"

Jonathan writes:
Second round of new iio device support, features and cleanups in the 4.8 cycle
Firstly some contact detail updates:
* NXP took over freescale. Update the mma8452 header to reflect this.
* Martin Kepplinger email address change in mma8452 header.
* Adriana Reus has changed email address. Update .mailmap.
* Matt Ranostay has changed email address. Update .mailmap.
New Device Support
* max1363
- add the missing i2c_device_ids for a couple of parts so they can actually
be used.
* ms5867
- add device ids for ms5805 and ms5837 parts.
New Features
* ad5755
- DT support. This one was a bit controversial and under review for a long
time. Still no one could come up with a better solution.
* stx104
- add gpio support
* ti-adc081c
- Add ACPI device ID matching.
Core changes
* Refuse to register triggers with duplicate names. There is no way to
distinguish between them so this makes no sense. A few drivers do not
generate unique names for each instance of the device present. We can't
fix this without changing ABI so leave them and wait for someone to
actually take the rare step of two identical accelerometers on the same
board.
* buffer-dma
- use ARRAY_SIZE in a few appropriate locations.
Tools
* Fix the fact that the --trigger-num option in generic_buffer didn't allow
0 which is perfectly valid in the ABI.
Cleanups
* as3935
- improve error reporting.
- remove redundant zeroing of a field in iio_priv.
* gp2ap020a00f
- use the iio_device_claim_*_mode helpers rather than open coding locking
around mode changes.
* isl29125
- use the iio_device_claim_*_mode helpers rather than open coding locking.
* lidar
- use the iio_device_claim_*_mode helpers rather than open coding locking.
* mma8452
- more detail in devices supported description in comments (addresses and
similar)
* sca3000
- add a missing error check.
* tcs3414
- use the iio_device_claim_*_mode helpers rather than open coding locking.
* tcs3472
- use the iio_device_claim_*_mode helpers rather than open coding locking.

Replace the code that guarantees the device stays in direct mode
with iio_device_claim_direct_mode() which does same. Includes a
tiny bit of refactoring (single case -> if) and simplified return
flow.
Also prevents a theoretical race condition by effectively taking the lock
a little earlier than before.

Using the struct i2c_device->id field for naming the light sensor
is a bad idea: when booting from the pure device tree this is NULL
and that causes the device not to have the "name" property in
sysfs and that in turn confuses the "lsiio" command to stop listing
devices.
So instead of using the device .id, use the hard string "bh1780",
which works just fine.

The code in runtime_[suspend|resume] was assuming that the
i2c client data was the bh1780 state container, but it contains
the IIO device. So first dereference the IIO device from the
i2c client, then get the state container using the iio_priv()
call.

This is not implemented and doesn't really make sense because IIO
proximity is unit-less.
Remove IIO_CHAN_INFO_SCALE from info_mask because so that the _scale
sysfs entry won't appear. This fixes userspace tools like generic_buffer
which abort when reads returns an error.

When writing a value using direct reg access from debugfs
we need to return and not fall through to reading the

First round of IIO new device support, features and cleanups for the 4.8 cycle.
New device support
* ads1015
- add ads1115 support
* bma220 accelerometer
- new driver
- triggered buffer support.
* bmc150
- add bmm150 support.
* bmp280
- bme280 support with addition of humidity channel.
* max5487 potentiometer
- new driver
* MMA7660FC accelerometer.
- New driver
* st-pressure
- support for the lps22hb
* loop trigger.
- This one is *nasty* but we have real applications (parrot drones) where
it is useful. The trigger basically spins as hard as it can firing off
a new trigger each time all triggered devices come back to say they are
done. It doesn't hang a machine even when doing it on a dummy driver.
A lot nicer than having this implemented within lots of device drivers
anyway.
Core stuff
* Add support to create IIO devices via configfs (similar to we did for
triggers a while back) + docs.
* New channel types
- IIO_ELECTRICAL_CONDUCTIVITY
* Couple of MAINTAINERS patches to list the device tree bindings.
* Make trigger ops structure non optional (comment fix). It hasn't been for
an awful long time, but that's not what the description said.
New features
* ak8975
- support adapters that are limited to byte data only by allowing the
emulated block read i2c function that was recently introduced.
* atlas-ph
- support atlas-ec (electrical conductivity sensor)
* bmi160
- add available frequency and scale attributes to make the driver
more user friendly (and avoid having to read the datasheet to know
what will work).
* dummy
- move creation to configfs interface. It's not real hardware so we
are not that worried about the ABI breakage ;)
* mma8452
- oversampling ration support
* nau7802
- expose available gains to make life easier for userspace.
* st-sensors
- allow use of emulation for SMBus block reads as all the st parts support
it.
* ti-ads1015
- list datasheet names to allow their use by inkernel consumers.
* Various module alias additions to help auto probing. Drop one redundant one
as well.
Cleanups
* ad7266, ad7476, ad7887, ad7923, ad799x
- use direct mode claim function rather than open coding it during sensor
read (prevents switching on buffers mid read).
* ad7793, ad7791
- use direct mode claim to prevent frequency changes when buffers running.
* afe440x - These are ABI breaking but the driver requires custom userspace
code to do anything useful anyway and that is still being written and under
control of TI. Ultimately we may have other libraries to do pulse
oximetry with these devices but we aren't aware of any yet.
- kernel-doc format fixes
- drop ifdef fun around of_match_ptr - it's not worth the mess to save
a tiny amount of space.
- drop some unnecessary register initializations.
- drop the weird locked gain modes as they gain us nothing (can just set
all gains separately).
- remove handling of offset attributes seeing as no channels actually have
them (oops)
- Drop the LED3 input channel as it's an alias for ALED2.
- *big one* remove channel names - an experiment that turned out to not
make sense - see patch for details.
- use regmap fields to clean up code.
- tie the tia gain stages to appropriate channels in the ABI as that is
what they really effect. Same with the LED currents.
- cleanout some unused defines and fix a missnamed one.
* atlas-ph
- reorganise to allow support of other similar parts.
* bmc150
- document supported chips in kconfig help.
* jsa1212
- drop an unneeded i2c functionality check for functionality the driver
doesn't use.
* mxs-lradc
- simply touch screen registration code.
- remove the touch screen unregister as all devm based now.
- disable only those channels that are masked in hardware stop (others
are already dealt with elsewhere)
* st-sensors
- unexport st_sensors_get_buffer_element as nothing outside the st-sensors
core driver uses it.
- fix handling of failure to start up regulators.
* tpl0102
- drop an i2c functionality test for features that aren't needed.
* ti-am335x
- use variable name rather than type in sizeof for clarity.
- use SIMPLE_DEV_PM_OPS helper macro to tidy up a bit.
Tools
* Add install / uninstall to makefile. Someone cares, so presumably
some people will find it useful!
* generic_buffer
- rename to iio_generic_buffer to line up with other tools.
- handle cleanup when receiving signals
- Add a --device-num option and a --trigger-num option rather than
relying on naming which doesn't work if you have two of the same part.

This driver does not call i2c_smbus_read|write_byte_data(),
so remove the corresponding functionality test. It uses regmap
to handle byte transfers transparently.

2nd set of new device support, features and cleanup for IIO in the 4.7 cycle.
Bit of a bumper set for new drivers but plenty of other stuff here as well!
New device support
* ad5592R ADC/DAC
- new driver supporting ad5592r and ad5593r combined ADC/DAC and gpio chips.
* Aosong am2315 relative humidity
- new driver with triggered buffer support in follow up patch.
* bmi160 imu
- new driver
* bmp280
- bmp180 support - note there is support in the misc/bmp085 driver. Intent
is to remove that driver long term.
* invensense mpu6050
- cleanup leading to explicit support of mpu9150 with a good few cleanups
along the way.
* Hope RF hp03 pressure and temperature sensor.
- new driver
* maxim DS1803 potentiometer
- new driver
* maxim max44000 light and proximity sensor
- new driver built in a series of steps to support pretty much everything.
* ROHM BH1780 light sensor
- new driver. There is an existing driver in misc that this is pretty much
intended to replace. The discussion on whether to support the non standard
interface of that driver is some way is continuing.
* st-gyro
- lsm9ds0-gyro. The accel/magn side of this will take a while longer as
extensions to the st library are needed for cases where two types of sensor
share a single i2c address.
* ti-adc081c
- support the adc101c and adc121c
* Vishay VEML6070 UV sensor
- new driver.
New features
* core
- devm_ APIs for channel_get and channel_get_all. The first user of these
is the generic ADC based thermal driver. As it is going through the
thermal tree these will be picked up as a patch to that next cycle as that
is how the author preferred to do it.
- mounting matrix support. This new core support allows devices to provide
to userspace (typically from the device tree) allowing compensation for how
the sensor is mounted on the device. First examples are on UAVs but it
has a more mundane use on typical phone where the chip may be on the front
or the back of the circuit board and soldered at any angle. Includes
support for this ABI in ak8975 (which has an older interface, now
deprecated) and mpu6050.
* tools
- add a -a option to enable all available channels in generic_buffer sample.
Makes it somewhat easier to use.
* adis library and drivers
- support manual self test flag clearing. This has technically been broken
for a very long time - result is an offset on readings as the applied field
is on all the time.
* ak8975
- triggered buffer support
* bmc150
- spi support (including splitting the driver into core and i2c parts)
* bmp280
- oversampling support.
* dht11
- improved logging - useful to debug timing issues on this quirky device.
* st-sensors
- read each channel invidivually as not all support the optimization of
reading in bulk. This is technically a fix, but will need to be backported
if desired.
- support open drain and shared interrupts.
* ti-adc081c
- triggered buffer support.
Cleanups
* inkern
- white space fix.
* ad7606
- use the iio_device_claim_direct_mode call rather than open coding equiv.
* ad799x
- white space fix.
* ad9523
- unsigned -> unsigned int
* apds9660
- brace location tidying up.
- silence an uninitialized variable warning.
* ak8975
- else and brace on same line fix.
* at91_adc
- white space fixes.
* bmc150
- use regmap stored copy of the device pointer rather than having an
additional copy.
* bmg160
- use regmap stored copy of the device pointer rather than having an
additional copy.
* hid-sensors
- white space fixes.
* mcp3422
- white space fix.
* mma7455
- use regmap to retrieve the device struct rather than carrying another copy
in the private data.
* ms_sensors
- white space fix.
* mxs-lradc
- move current bindings out of staging - some will be shortly deprecated but
the reality is that we have device trees out there using them so they will
need to be supported for some time. They accidentally got left behind
when the driver graduated from staging.
- white space cleanup.
- set INPUT_PROP_DIRECT.
- move ts config into a better function.
- move the STMP reset out of the ADC init.
* vf610_adc
- case label indenting fix.

This patch exposes ALSTIM as illuminance_integration_time and ALSPGA as
illuminance_scale.
Changing ALSTIM also changes the number of bits available in the data
register. This is handled inside raw value reading because:
* It's very easy to shift a few bits
* It allows SCALE and INT_TIME to be completely independent controls
* Buffer support requires constant scan_type.realbits per-channel

This is exposed as an output channel with "led" as an extend_name.
Other sensors also have support for controlling an external LED. It's
not clear that simply exposing an undecorated output channel is the
correct approach.

This is a reimplementation of the old misc device driver for the
ROHM BH1780 ambient light sensor (drivers/misc/bh1780gli.c).
Differences from the old driver:
- Uses the IIO framework
- Uses runtime PM to idle the hardware after 5 seconds
- No weird custom power management from userspace
- No homebrewn values in sysfs
This uses the same (undocumented) device tree compatible-string
as the old driver ("rohm,bh1780gli").

First round of IIO fixes for the 4.6 cycle.
Again I've ended up with two early fix sets, depending on whether they are
dependent on elements of the merge window or simply came in after I had
patches with that dependency already, vs older fixes that were just too
late for the last cycle. This first set is for the older ones.
- max1353
* Add a missing adc to max1363_id - the driver has supported the
max11644-11647 for a while, but as they weren't in the id table there
was no way of actually initializing it.
* Fix a wrong reference voltage for the above models. Given you couldn't
initialize the driver for these parts without patching, no one noticed
that the reference voltage used in computing the scaling was wrong.
- apds9960
* The fifo last enelement was read twice (and hence pushed out twice) due
to a small logic bug.

Correct issue that the last entry in FIFO was being read twice due
to an incorrect decrement of entry count variable before condition
check.

GPIO handling code has been removed from the drivers (since
this is now handled by the ACPI core) in commit 0f0796509c07 ("iio:
remove gpio interrupt probing from drivers that use a single interrupt").
Remove the include for linux/gpio/consumer.h since it is no longer
used.

flush_scheduled_work is scheduled for deprecation.
Replace cancel_delayed_work and flush_scheduled_work with
cancel_delayed_work_sync instead to ensure there is no pending or
running work item.
Since there is only one work item, chip->poweroff_work, there are
no further dependencies of flush_scheduled_work().

First set of IIO fixes for the 4.5 cycle.
This set comprises those not dependent on patches in the 4.5 merge cycle.
A second set will follow shortly with ones that are.
* core in kernel interfaces
- fix a possible NULL dereference that is a theoretical possibility
via odd usage of iio_channel_release. Pretty much a hardening of
the interface, but observed in the wild with the twl4030_charger
driver.
* acpi-als
- report the data as processed as it is in lux. This fixes a wrong
use of the IIO ABI. However, old _raw version retained to avoid
breaking any userspace in the wild that is relying on that (none
known but it doesn't hurt us much to retain it)
* ade7753
- fix some error handling to avoid use of unitialized data.
* ltr501
- use a signed return type for ltr501_match_samp_freq so as to allow
returning of an error code.
* mcp4725
- set name field of struct iio_dev to ensure the sysfs name attribute
doesn't give NULL.
* mpl115
- temperature offset sign is wrong.
* stk8ba50
- IIO_TRIGGER dependency added
* ti_am335x_adc
- Label buffer as a software buffer. It's actually a hybrid of a
true hardware buffer feeding a kfifo, but the meaning of these fields
has changed a little recently and in this case it should be labeled
a software buffer ensure it is allowed to use the kfifo.
* vf610_adc
- HAS_IOMEM dependency

As per the ACPI specification (Revision 5.0) [1], the data coming
from the sensor represent the ambient light illuminance reading
expressed in lux. So use IIO_CHAN_INFO_PROCESSED to signify that
the data are pre-processed.
However, to keep backward ABI compatibility, the IIO_CHAN_INFO_RAW
bit is not removed.
[1] http://www.acpi.info/DOWNLOADS/ACPIspec50.pdf
This issue has also been responsible for at least one userspace bug
report hence marking what is a small semantic fix really for stable.
