pointer passed to `kfree()` is non-NULL, so remove that check.

Merge tag 'iio-for-3.12b' of git://git./linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

Second round of new drivers, features and cleanups for IIO in the 3.12 cycle.

New driver:

1) tmp006 IR thermopile driver.  This is an unusual temperature sensor
   and was taken in to IIO with the knowledge and agreement of a hwmon
   maintainer.
   It measures remote temperature using infrared emissions.
   I guess taking this may mean we have to fight off submissions of
   devices much more suited to hwmon but such is life and we end up
   doing this from time to time already.

2) twl6030 adc driver.

Cleanups:

1) More devm_* cleanups following on from the introduction of
   devm_iio_device_alloc.  Mostly an heroic effort from
   Sachin Kamat!

2) Introduce devm_iio_trigger_alloc etc to handle trigger
   allocation and deallocation in a managed fashion.  There
   aren't as many instances of triggers as devices, but this
   will allow futher reduction in error patch complexity in
   some of our most complex drivers making it a very good thing.
3) Trivial removal of unused defines in adjd_s311

4) Drop some write_raw_get_fmt callbacks where they were only
   returning the default value.

5) Change mxs-lradc realbits to 12.  Whilst an 18bit register
   is used on the device, in its current mode only 12 bits of
   useful data are returned.  For now the packing is unchanged
   in the buffer and this change mainly effects the input support
   in the driver.

iio: twl6030-gpadc: TWL6030, TWL6032 GPADC driver

The GPADC is general purpose ADC found on TWL6030, and TWL6032 PMIC,
known also as Phoenix and PhoenixLite.

The TWL6030 and TWL6032 have GPADC with 17 and 19 channels
respectively. Some channels have current source and are used for
measuring voltage drop on resistive load for detecting battery ID
resistance, or measuring voltage drop on NTC resistors for external
temperature measurements. Some channels measure voltage, (i.e. battery
voltage), and have voltage dividers, thus, capable to scale voltage.
Some channels are dedicated for measuring die temperature.

Some channels are calibrated in 2 points, having offsets from ideal
values kept in trim registers. This is used to correct measurements.

The differences between GPADC in TWL6030 and TWL6032:
- 10 bit vs 12 bit ADC;
- 17 vs 19 channels;
- channels have different purpose(i.e. battery voltage
  channel 8 vs channel 18);
- trim values are interpreted differently.

Based on the driver patched from Balaji TK, Graeme Gregory, Ambresh K,
Girish S Ghongdemath.

iio: mxs-lradc: change the realbits to 12

The LRADC virtual channels have an 18 bit field to store the sum of up
to 2^5 accumulated samples. The read_raw function however only operates
over a single sample (12 bit resolution).
In order to use this field for scaling operations, we need it to be the
exact resolution value of the LRADC.
Besides, the driver was using an 18 bit mask (LRADC_CH_VALUE_MASK) to
report touch coordinates to userland. A 12 bit mask should be used instead
or else the touch libraries will expect a coordinates range between 0
and 0x3ffff (18 bits), instead of between 0 and 0xfff (12 bits).

android/sync: use get_unused_fd_flags(O_CLOEXEC) instead of get_unused_fd()

Macro get_unused_fd() is used to allocate a file descriptor with
default flags. Those default flags (0) can be "unsafe":
O_CLOEXEC must be used by default to not leak file descriptor
across exec().

Instead of macro get_unused_fd(), functions anon_inode_getfd()
or get_unused_fd_flags() should be used with flags given by userspace.
If not possible, flags should be set to O_CLOEXEC to provide userspace
with a default safe behavor.

In a further patch, get_unused_fd() will be removed so that
new code start using anon_inode_getfd() or get_unused_fd_flags()
with correct flags.

This patch replaces calls to get_unused_fd() with call to
get_unused_fd_flags(O_CLOEXEC) following advice from Erik Gilling.
