Merge tag 'fixes-for-3.14d' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus
Jonathan writes: Fourth set of IIO fixes for the 3.14 kernel. A single line patch fixing a regression that was introduced in 3.13 in the reworking of the mxs touch screen and ADC drivers to be interrupt rather than polling driven. It resulted in a stray double reporting of the release coordinate in the touch screen driver. The bug lay in the adc side of the driver which left the statemachine in the wrong state.
