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:
  Input: iforce - wait for command completion when closing the device
  Input: twl4030-pwrbutton - switch to using threaded IRQ
  Input: twl4030_keypad - switch to using threaded IRQ
  Input: lifebook - add CONFIG_DMI dependency
  Input: wistron - fix test for CONFIG_PM
  Input: psmouse - fix compile warning in hgpk module
  Input: matrix-keypad - handle cases when GPIOs can't be wakeup sources
  Input: iforce - fix oops on device disconnect
  Input: ff-memless - add notion of direction to for rumble effects
  Input: ff-memless - another fix for signed to unsigned overflow
  Input: ff-memless - start playing FF effects immediately
  Input: serio - do not mark kseriod freezable anymore
  Input: speed up suspend/shutdown for PS/2 mice and keyboards
