Merge tag 'iio-for-3.17a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First round of new drivers, cleanups and functionality for the 3.17 cycle.

New drivers
* t5403 barometric pressure sensor
* kxcjk1013 accelerometer (with a locking followup fix).
* ak09911 digital compass

Documentation
* ABI docs for proximity added (interface has been there a long time but
  somehow snuck through without being documented)
* Move iio-trig-sysfs documentation out of staging (got left behind when
  the driver moved some time ago).

Cleanups
 * drop the timestamp argument from iio_trigger_poll(_chained) as
   nothing has been done with it for some time.
 * ad799x kerneldoc for ad799x_chip brought up to date.
 * replace a number of reimplementations of the GENMASK macro and
   use the BIT macro to cleanup a few locations.
 * bring the iio_event_monitor example program up to date with new
   device types.
 * fix some incorrect function prototypes in iio_utils.h example code.
 * INDIO_RING_TRIGGERED to INDIO_BUFFER_TRIGGERED fix in docs. This
   got left behind after we renamed it a long time back.
 * fix error handling in the generic_buffer example program.
 * small tidy ups in the iio-trig-periodic-rtc driver.
 * Allow reseting iio-trig-periodic-rtc frequency to 0 (default) after
   it has changed.
 * Trivial tidy ups in coding style in iio_simply_dummy
