Third round of fixes for IIO in the 3.14 cycle.
Fixes to 2 Capella light sensor drivers where the units of the integration
time reported to userspace were out be a factor of a thousand.
These patches are as large as they are purely due to a variable rename
tied up with the incorrect scale. The actual change is only a couple of lines.
1 patch dropping L3GD20H from the st gyroscope driver. It never actually
worked as the address set is different from any others supported by the
driver currently. An additional patch enables correct support for this
part but is too large to sensibly apply as a fix to some support that never
actually allowed the driver to be successfully probed on this part.

The driver was not able to manage the sensor: during probe function
and wai check, the driver stops and writes: "device name and WhoAmI mismatch."
The correct value of L3GD20H wai is 0xd7 instead of 0xd4.
Dropped support for the sensor.

But, print more then the thousand second. when call *_integration_time attribute.
Because read_integration_time function return IIO_VAL_INT.
read integration time function is changed return IIO_VAL_INT_PLUS_MICRO;
And then .write_raw_get_fmt callback function for parse a fixed-point number from a string.

Fourth set of IIO fixes for the 3.14 kernel.
A single line patch fixing a regression that was introduced in 3.13 in the
reworking of the mxs touch screen and ADC drivers to be interrupt rather
than polling driven. It resulted in a stray double reporting of the release
coordinate in the touch screen driver. The bug lay in the adc side
of the driver which left the statemachine in the wrong state.

Releasing the touchscreen lets the internal statemachine left in a wrong state.
Due to this the release coordinate will be reported again by accident when the next
touchscreen event happens. This change sets up the correct state when waiting
for the next touchscreen event.
This has led to reported issues with calibrating the touchscreen.
Bug was introduced somewhere in the series that began with
18da755de59b406ce2371a55fb15ed676eb08ed2
Staging/iio/adc/touchscreen/MXS: add proper clock handling
in which the way this driver worked was substantially changed
to be interrupt driven rather than relying on a busy loop.
This was a regression in the 3.13 kernel.

A selective retransmission request (SRR) is a fibre-channel
protocol control request which provides support for requesting
retransmission of a data sequence in response to an issue such as
frame loss or corruption. These events are experienced
infrequently in fibre-channel based networks which makes
it difficult to test and assess codepaths which handle these
events.
We were fortunate enough, for some definition of fortunate, to
have a metro-area single-mode SAN link which, at 10 GBPS
sustained load levels, would consistently generate SRR's in
a SCST based target implementation using our SCST/in-kernel
Qlogic target interface driver. In response to an SRR the
in-kernel Qlogic target driver immediately panics resulting
in a catastrophic storage failure for serviced initiators.
The culprit was a debug statement in the qla_target.c file which
does not verify that a pointer to the SCSI CDB is not null.
The unchecked pointer dereference results in the kernel panic
and resultant system failure.
The other two references to the SCSI CDB by the SRR handling code
use a ternary operator to verify a non-null pointer is being
acted on. This patch simply adds a similar test to the implicated
debug statement.
This patch is a candidate for any stable kernel being maintained
since it addresses a potentially catastrophic event with
minimal downside.

This patch fixes a bug in sbc_dif_copy_prot() where the updated addr
offset did not take into account the case where the associated
scatterlist had not been incremented.
This addresses the case where incoming protection scatterlists may
contain a length smaller than PAGE_SIZE across multiple entires,
when the target protection scatterlists are always being explicitly

This patch performs configfs_depend_item() during TPG enable for
base_tpg (eg: non-NPIV) ports, and configfs_undepend_item() during
TPG disable for base_tpg.
This is done to ensure that any attempt to configfs rmdir a base_tpg
with active NPIV ports will fail with -EBUSY, until all associated
NPIV ports have been explicitly shutdown and base_tpg disabled.
Note that the actual configfs_[un]depend_item() is done from seperate
process context, as these are not intended to be called directly
from configfs callbacks.

This patch adds seperate logic for NPIV specific enable/disable
attribute logic, as NPIV vs. non-NPIV enable/disable ends up being
different enough to warrent seperate logic for setting configfs
tpg_group dependencies in the non-NPIV case.

This patch adds an check to qlt_stop_phase1() to avoid shutdown
when the base_vha contains a non-zero fc_host->npiv_vports_inuse
count.
This includes holding qla_tgt_mutex in qlt_stop_phase1() between
the fc_host->npiv_vports_inuse check + setting of tgt->tgt_stop to
avoid a possible race between qlt_lport_register() -> tcm_qla2xxx
-> tcm_qla2xxx_lport_register_npiv_cb() calling fc_vport_create().

This patch closes a race between qlt_lport_register() and
tcm_qla2xxx callback logic by holding qla_tgt_mutex before
making the callback.
In order for this to work, the qlt_add_target() and
qlt_remove_target() code has been changed to avoid the
accessing qla_tgt_mutex + list_[add,del] for NPIV enabled
ports.
This bug introduced in v3.14-rc1 code with commit 49a47f2.

imx25 did not work without a firmware previously.
This patch adds a DT compatible to pass the correct data with the
default script addresses for imx25.
Add imx25 compatible to the list of compatibles in the binding

It appears that in the DMA40 driver the DMA tasklet will very
often dereference memory for a descriptor just free:d from the
DMA40 slab. Nothing happens because no other part of the driver
has yet had a chance to claim this memory, but it's really
nasty to dereference free:d memory, so let's check the flag
before the descriptor is free and store it in a bool variable.

Pull ACPI and power management fixes from Rafael Wysocki:
"These three commits fix a recent intel_pstate regression and two old
bugs that should be fixed in -stable too, one in the ACPI processor
driver and one in the firmare loader.
Specifics:
- One of the recent intel_pstate driver fixes introduced a rounding
error that on some systems causes the frequency to be stuck at the
lowest level forever. Fix from Dirk Brandewie.
- The firmware_class driver's PM notifier doesn't handle the
PM_RESTORE_PREPARE event during hibernation image restore and that
leads to a deadlock on umhelper_sem in __usermodehelper_disable().
Fix from Sebastian Capella.
- acpi_processor_set_throttling() abuses set_cpus_allowed_ptr() in a
nasty way which triggers the WARN_ON_ONCE() in wq_worker_waking_up()
among other things. Fix from Lan Tianyu"

acpi_processor_set_throttling() uses set_cpus_allowed_ptr() to make
sure that the (struct acpi_processor)->acpi_processor_set_throttling()
callback will run on the right CPU. However, the function may be
called from a worker thread already bound to a different CPU in which
case that won't work.
Make acpi_processor_set_throttling() use work_on_cpu() as appropriate
instead of abusing set_cpus_allowed_ptr().

During restore, pm_notifier chain are called with
PM_RESTORE_PREPARE. The firmware_class driver handler
fw_pm_notify does not have a handler for this. As a result,
it keeps a reader on the kmod.c umhelper_sem. During
freeze_processes, the call to __usermodehelper_disable tries to
take a write lock on this semaphore and hangs waiting.

Commit fcb6a15c2e (intel_pstate: Take core C0 time into account for
core busy calculation) introduced a regression on some processor SKUs
supported by intel_pstate. This was due to the truncation caused by
using integer math to calculate core busy and C0 percentages.
On a i7-4770K processor operating at 800Mhz going to 100% utilization
the percent busy of the CPU using integer math is 22%, but it actually
is 22.85%. This value scaled to the current frequency returned 97
which the PID interpreted as no error and did not adjust the P state.
Tested on i7-4770K, i7-2600, i5-3230M.
Fixes: fcb6a15c2e7e (intel_pstate: Take core C0 time into account for core busy calculation)

When remapping a block to the cache's fast device that is larger than
2TB we must not truncate the destination sector to 32bits. The 32bit
temporary result of from_cblock() was being overflowed in
remap_to_cache() due to the logical left shift.
Use an intermediate 64bit type to store the 32bit from_cblock() result
to fix the overflow.
