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

Pull input updates from Dmitry Torokhov:
 "A bit later than I would want, but the changes are very minor - a few
  new device IDs for new hardware in existing drivers, fix for battery
  in Wacom devices not be considered system battery and cause emergency
  hibernations, and a couple of other bug fixes"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: ALPS - add support for model found on Dell XT2
  Input: wacom - add support for ISDv4 0x10E sensor
  Input: wacom - add support for ISDv4 0x10F sensor
  Input: wacom - export battery scope
  Input: cm109 - convert high volume dev_err() to dev_err_ratelimited()
  Input: move name/timer init to input_alloc_dev()
  Input: i8042 - i8042_flush fix for a full 8042 buffer
  Input: pxa27x_keypad - fix NULL pointer dereference
