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

Browse Source 
Pull input layer fixes from Dmitry Torokhov:
 "The main change is to fix breakage in Elantech driver introduced by
  the recent commit adding trackpoint reporting to protocol v4.  Now we
  are trusting the hardware to advertise the trackpoint properly and do
  not try to decode the data as trackpoint if firmware told us it is not
  present"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: xpad - use proper endpoint type
  Input: elantech - trust firmware about trackpoint presence
  Input: synaptics - adjust min/max on Thinkpad E540
