Without ANON_INODES, we get this build error:
drivers/built-in.o: In function `iio_event_getfd':
:(.text+0x14bf18): undefined reference to `anon_inode_getfd'
All other users explicitly select this symbol, so we should
do the same thing here.

Added an API to allow client drivers to turn ON and OFF sensors for
quick read. Added data_read as counting varaible instead of boolean,
so that sensor is powered off only when last user released it.

HID sensor hub specify a default unit and alternative units. This
along with unit exponent can be used adjust scale. This change
change HID sensor data units to IIO defined units for each
sensor type. So in this way user space can use a simply use:
"(data + offset) * scale" to get final result.

This function returns a bool, that is supposed to be false when something
goes wrong. It's assumed this way by its lone calling function (which is
SetRFPowerState8190(), line 1445 of rtl8192e/rtl8192e/r8192E_phy.c)
Despite of this, this procedure returns non-null enumerations values or
negative codes instead. This patch fixes this.

`s->async->subdevice` in `comedi_poll()` points to the same `struct
comedi_subdevice` as `s`, so the double pointer reference is redundant.
Just use `s`.
(`s->async->subdevice` is initialized by
`__comedi_device_postconfig_async()` in
"drivers/staging/comedi/drivers.c" and doesn't change.)

For the mode configured by the `INSN_CONFIG_SET_COUNTER_MODE` comedi
instruction for the counter subdevice channels supported by this module,
the upper bound should be `I8254_MODE5 | I8254_BCD` ((5 << 1) | 1)
rather than `I8254_MODE5 | I8254_BINARY` ((5 << 1) | 0). Fix it.

The upper bound check on the `mode` parameter of `i8254_set_mode()` and
`i8254_mm_set_mode()` is incorrect. The `mode` parameter value consists
of a mode number in the range 0 to 5 in bits 3..1 {represented by the
constants `I8254_MODE0` (0 << 1) through to `I8254_MODE5` (2 << 1)} ORed
with a BCD/binary flag in bit 0 {represented by the constants
`I8254_BINARY` (0) and `I8254_BCD` (1)}. The maximum allowed value
ought to be `I8254_MODE5 | I8254_BCD` ((5 << 1) | 1), but is currently
`I8254_MODE5 | I8254_BINARY` ((5 << 1) | 0). Fix it.
None of the comedi drivers use `I8254_BCD` but some of the low-level
drivers allow user-space to configure the counter mode, so all legal
values ought to be allowed. However, it's pretty unlikely anyone would
want to set the counters to count in BCD (binary coded decimal) so the
bug is not that significant.

As pointed out by Ian Abbott, the i8254_load() function does not
use the I8254_MODE* values to specify the "mode".
The labpc_counter_load() function in this driver is passed an
I8254_MODE* value so we need to use the i8254_set_mode() and
i8254_write() helpers instead of i8254_load() to program the
timers.
The calls to labpc_counter_load() will not fail so change the
return to void and remove all the unnecessary error handling.
Similarly, change the return type of labpc_counter_set_mode() to
void and remove the unnecessary error handling.
