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

Pull input updates from Dmitry Torokhov:
 "This fixes recent regression where /dev/input/mice got assigned wrong
  device node which messed up setups with static /dev, and a regression
  in ads7846 GPIO debounce setup."

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  ARM - OMAP: ads7846: fix pendown debounce setting
  Input: ads7846 - enable pendown GPIO debounce time setting
  Input: mousedev - move /dev/input/mice to the correct minor
  Input: MT - document new 'flags' argument of input_mt_init_slots()
