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

Browse Source 
Pull 2nd round of input updates from Dmitry Torokhov:
 - update to Wacom driver to support wireless devices
 - update to Sentelci touchpad driver to support newer hardware
 - update to gpio-keys driver to support "interrupt-only" keys
 - fixups to earlier commits

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: wacom - check for allocation failure in probe()
  Input: tegra-kbc - allocate pdata before using it
  Input: amijoy - add missing platform check
  Input: wacom - wireless battery status
  Input: wacom - create inputs when wireless connect
  Input: wacom - wireless monitor framework
  Input: wacom - isolate input registration
  Input: sentelic - improve packet debugging information
  Input: sentelic - minor code cleanup
  Input: sentelic - enabling absolute coordinates output for newer hardware
  Input: sentelic - refactor code for upcoming new hardware support
  Input: gpio_keys - add support for interrupt only keys
  Input: gpio_keys - consolidate key destructor code
  Input: revert "gpio_keys - switch to using threaded IRQs"
  Input: gpio_keys - constify platform data
  Input: spear-keyboard - remove kbd_set_plat_data()
