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

Browse source 
Pull input updates from Dmitry Torokhov:
 "An update to ALPS to support devices on Dell XT2 (hopefully working
  better this time around and although it is largish it should not
  affect any other ALPS devices) and a tiny update to Elantech driver to
  support newer devices as well.

  Also a coupe of new input event codes have been defined"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: ALPS - add support for DualPoint device on Dell XT2 model
  Input: elantech - add support for newer (August 2013) devices
  Input: add SW_MUTE_DEVICE switch definition
  Input: usbtouchscreen - separate report and transmit buffer size handling
  Input: sur40 - suppress false uninitialized variable warning
  Input: add key code for ambient light sensor button
  Input: keyboard - "keycode & KEY_MAX" changes some keycode values
