Merge tag 'iio-for-v3.7a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23...

First set of IIO rework and new drivers for 3.7 cycle.

New MXS adc driver form Marek Vasut with a minor addition
to the example code to support 4 byte reads.

First of I suspect many devm conversion patches form Julia Lawall
Some module_platform_driver uses that somehow got missed the
first time around.

Couple of other useful cleanups.
