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.

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.

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).

staging: ozwpan: Separate success & failure case for oz_hcd_pd_arrived()
This patch separates success & failure block along with fixing
following issues:-
1. The way oz_hcd_pd_arrived() looks now it's easy to think we free "ep" but
actually we do this spaghetti thing of setting it to NULL on success.
2. It is hard to read it because there are unlocks scattered throughout.
3. Currently we set "ep" to NULL on the success path and then test it and or
free it. In current code you have to scroll to the start of the function
to read code.

zram: don't grab mutex in zram_slot_free_noity
[1] introduced down_write in zram_slot_free_notify to prevent race
between zram_slot_free_notify and zram_bvec_[read|write]. The race
could happen if somebody who has right permission to open swap device
is reading swap device while it is used by swap in parallel.
However, zram_slot_free_notify is called with holding spin_lock of
swap layer so we shouldn't avoid holing mutex. Otherwise, lockdep
warns it.
This patch adds new list to handle free slot and workqueue
so zram_slot_free_notify just registers slot index to be freed and
registers the request to workqueue. If workqueue is expired,
it holds mutex_lock so there is no problem any more.
If any I/O is issued, zram handles pending slot-free request
caused by zram_slot_free_notify right before handling issued
request because workqueue wouldn't be expired yet so zram I/O
request handling function can miss it.
Lastly, when zram is reset, flush_work could handle all of pending
free request so we shouldn't have memory leak.
NOTE: If zram_slot_free_notify's kmalloc with GFP_ATOMIC would be
failed, the slot will be freed when next write I/O write the slot.
