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

Browse Source 
* '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..

@@ -205,20 +205,6 @@ Who: Len Brown <len.brown@intel.com>
---------------------------
What: Compaq touchscreen device emulation
When: Oct 2007
Files: drivers/input/tsdev.c
Why: The code says it was obsolete when it was written in 2001.
tslib is a userspace library which does anything tsdev can do and
much more besides in userspace where this code belongs. There is no
longer any need for tsdev and applications should have converted to
use tslib by now.
The name "tsdev" is also extremely confusing and lots of people have
it loaded when they don't need/use it.
Who: Richard Purdie <rpurdie@rpsys.net>
---------------------------
What: i2c-ixp2000, i2c-ixp4xx and scx200_i2c drivers
When: September 2007
Why: Obsolete. The new i2c-gpio driver replaces all hardware-specific
