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..
