   - The firmware_class driver's PM notifier doesn't handle the

     leads to a deadlock on umhelper_sem in __usermodehelper_disable().
     Fix from Sebastian Capella.

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.
