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.
