sched: don't cause task state changes in nested sleep debugging
Commit 8eb23b9f35aa ("sched: Debug nested sleeps") added code to report
on nested sleep conditions, which we generally want to avoid because the
inner sleeping operation can re-set the thread state to TASK_RUNNING,
but that will then cause the outer sleep loop not actually sleep when it
calls schedule.
However, that's actually valid traditional behavior, with the inner
sleep being some fairly rare case (like taking a sleeping lock that
normally doesn't actually need to sleep).
And the debug code would actually change the state of the task to
TASK_RUNNING internally, which makes that kind of traditional and
working code not work at all, because now the nested sleep doesn't just
sometimes cause the outer one to not block, but will cause it to happen
every time.
In particular, it will cause the cardbus kernel daemon (pccardd) to
basically busy-loop doing scheduling, converting a laptop into a heater,
as reported by Bruno Prémont. But there may be other legacy uses of
that nested sleep model in other drivers that are also likely to never
get converted to the new model.
This fixes both cases:
- don't set TASK_RUNNING when the nested condition happens (note: even
if WARN_ONCE() only _warns_ once, the return value isn't whether the
warning happened, but whether the condition for the warning was true.
So despite the warning only happening once, the "if (WARN_ON(..))"
would trigger for every nested sleep.
- in the cases where we knowingly disable the warning by using
"sched_annotate_sleep()", don't change the task state (that is used
for all core scheduling decisions), instead use '->task_state_change'
that is used for the debugging decision itself.
(Credit for the second part of the fix goes to Oleg Nesterov: "Can't we
avoid this subtle change in behaviour DEBUG_ATOMIC_SLEEP adds?" with the
suggested change to use 'task_state_change' as part of the test)

Second round of IIO new drivers, functionality and cleanups for the 3.20 cycle.
New drivers and device support:
* Capella cm3232 ambient light sensor driver.
* Freescale MMA9553 pedometer and activity monitor. Note this involved a
refactor of the mma9551 driver to pull out shared elements.
* Samsung sensor hub (as used in the galaxy gear 2 watch) Core support
and initial drivers (gyro and accelerometer) more to follow.
An additional fix was applied on top of this for a build issue
thrown up by the autobuilders on some platforms.
* Cosmic Circuits 10001 ADC driver
* Qualcomm SPMI PMIC voltage ADC driver (current adc merged a while back).
* Add binding for AK8963 (in capitals) as unfortunately there are bios'
out there not using lower case.
New functionality
* Add newe operating mode to the core to allow for non triggered software
buffers. This is mostly semantics as previously drivers just claimed they
had a hardware buffer (when they didn't).
* Add distance channel type.
* Add energy channel type.
* Add velocity channel type and IIO_MOD_ROOT_SUM_SQUARED (i.e. speed when
our channel type is velocity).
* Add _debounce_count and _debounce_time filter attributes. Only really
make sense for counting types of measurements. First use is for avoiding
miss detection of steps prior to walking.
* Add change event type. This replaces the briefly present INSTANCE type
(which hadn't gained any users). It is more generic as it allows for
events say every 10 steps rather than every step.
* Add _calibweight attributes to the ABI (and core support). Used by
activity monitors to estimate energy use. Can imagine there will be
other uses for this one.
Driver new functionality
* mma9551 gains runtime pm support.
* hid-sensors gain PM support.
Cleanup
* Change calibheight unit to m from cm. As there are no prior users
and this was inconsistent with other distance units, it makes sense
to fix it before hte mma9553 driver which uses it.
* mpu6050 cleanups and devm_ use.
* as3935 switch over to PM ops.
* Fix a few format strings for signed vs unsigned.
* Fix tcs3414 missindentation
* Typo in industrialio-event
* Stop requiring IIO_TRIGGER for IIO_KFIFO_BUF as we have drivers that don't
need it. No one is quite sure why that dependency was there and it
seems to not matter.

iio: add driver for Freescale MMA9553
Add support for Freescale MMA9553L Intelligent Pedometer Platform.
The following functionalities are supported:
- step counter (counts the number of steps using a HW register)
- step detector (generates an iio event at every step the user takes)
- activity recognition (rest, walking, jogging, running)
- speed
- calories
- distance
To get accurate pedometer results, the user's height, weight and gender
need to be configured.
The specifications can be downloaded from:

i2c: sh_mobile: terminate DMA reads properly
DMA read requests could miss proper termination, so two more bytes would
have been read via PIO overwriting the end of the buffer with wrong
