  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

  ...

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..
