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..
