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

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (40 commits)
  Input: use full RCU API
  Input: remove tsdev interface
  Input: add support for Blackfin BF54x Keypad controller
  Input: appletouch - another fix for idle reset logic
  HWMON: hdaps - switch to using input-polldev
  Input: add support for SEGA Dreamcast keyboard
  Input: omap-keyboard - don't pretend we support changing keymap
  Input: lifebook - fix X and Y axis range
  Input: usbtouchscreen - add support for GeneralTouch devices
  Input: fix open count handling in input interfaces
  Input: keyboard - add CapsShift lock
  Input: adbhid - produce all CapsLock key events
  Input: ALPS - add signature for ThinkPad R61
  Input: jornada720_kbd - send MSC_SCAN events
  Input: add support for the HP Jornada 7xx (710/720/728) touchscreen
  Input: add support for HP Jornada 7xx onboard keyboard
  Input: add support for HP Jornada onboard keyboard (HP6XX)
  Input: ucb1400_ts - use schedule_timeout_uninterruptible
  Input: xpad - fix dependancy on LEDS class
  Input: auto-select INPUT for MAC_EMUMOUSEBTN option
  ...

Resolved conflicts manually in drivers/hwmon/applesmc.c: converting from
a class device to a device and converting to use input-polldev created a
few apparently trivial clashes..
