Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:

 - updates to Ilitech driver to support ILI2117

 - face lift of st1232 driver to support MT-B protocol

 - a new driver for i.MX system controller keys

 - mpr121 driver now supports polling mode

 - various input drivers have been switched away from input_polled_dev
   to use polled mode of regular input devices

 - other assorted cleanups and fixes
