iio: Require strict scan mask matching in hardware mode
In hardware mode we can not use the software demuxer, this means that the
selected scan mask needs to match one of the available scan masks exactly.
It also means that all attached buffers need to use the same scan mask.
Given that when operating in hardware mode there is typically only a single
buffer attached to the device this not an issue. Add a sanity check to make
sure that only a single buffer is attached in hardware mode nevertheless.

iio: __iio_update_buffers: Leave device in sane state on error
Currently when something goes wrong at some step when disabling the buffers
we immediately abort. This has the effect that the enable/disable calls are
no longer balanced. So make sure that even if one step in the disable
sequence fails the other steps are still executed.
The other issue is that when either enable or disable fails buffers that
were active at that time stay active while the device itself is disabled.
This leaves things in a inconsistent state and can cause unbalanced
enable/disable calls. Furthermore when enable fails we restore the old scan
mask, but still keeps things disabled.
Given that verification of the configuration was performed earlier and it
is valid at the point where we try to enable/disable the most likely reason
of failure is a communication failure with the device or maybe a
out-of-memory situation. There is not really a good recovery strategy in
such a case, so it makes sense to leave the device disabled, but we should
still leave it in a consistent state.
What the patch does if disable/enable fails is to deactivate all buffers
and make sure that the device will be in the same state as if all buffers
had been manually disabled.

iio: Replace printk in __iio_update_buffers with dev_dbg
While more verbose error messages are useful for debugging we should really
not put those error messages into the kernel log for normal errors that are
already reported to the application via the error code, when running in
non-debug mode.
Otherwise application authors might expect that this is part of the ABI and
to get the error they should scan the kernel log. Which would be rather
error prone itself since there is no direct mapping between a operation and
the error message so it is impossible to find out which error message
belongs to which error.

First round of new drivers, functionality and cleanups for the 4.2 cycle
New drivers / device support
* st sensors driver, lsm303dlh magnetometer support.
* ltr501 - support ltr301 and ltr559 chips.
New functionality
* IIO_CHAN_INFO_CALIBEMISSIVITY for thermopile sensors.
* kxcjk1013 - make driver operational with external trigger.
* Add iio targets to the tools Makefile.
Cleanups
* st sensors - more helpful error message if device id wrong or irq request
fails, explicitly make the Block Data Update optional rather
than relying on writes to address 0 not doing anything, make interrupt
support optional (Not always wired, and not all devices actually have
an interrupt line.)
* kxcjk-1013 white space additions for readability, add the KXCJ9000 ACPI
id as seen in the wild.
* sx9500 - GPIO reset support, refactor the GPIO interrupt code, add power
management, optimize power usage by powering down when possible, rename
the gpio interrupt pin to be more useful, trivial return path simplification,
trivial formatting fixes.
* isl29018 - move towards ABI compliance with a view to moving this driver
out of staging, add some brackets to ensure code works as expected. Note
there is no actual bug as the condition being tested is always true
(with current devices).
* ltr501 - add regmap support to get caching etc for later patches,
fix a parameter sanity check that always fails (bug introduced
earlier in this series), ACPI enumeration support,
interrupt rate control support, interrupt support in general and
integration time control support, code alignment cleanups.
* mma9553 - a number of little cleanups following a review from Hartmut
after I'd already applied the original driver patch.
* tmp006 - prefix some defines with TMP006 for consistency.
* tsl4531 - cleanup some wrong prefixes, presumably from copy and paste.
* mlx90614 - check for errors in read values, add power management,
add emissivity setting, add device tree binding documentation,
fix a duplicate const warning.
* ti_am335x_adc - refactor the DT parsing into a separate function.
