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

Browse source 
Pull input fixes from Dmitry Torokhov:

 - add sanity checks to USB endpoints in various dirvers

 - max77650-onkey was missing an OF table which was preventing module
   autoloading

 - a revert and a different fix for F54 handling in Synaptics dirver

 - a fixup for handling register in pm8xxx vibrator driver

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: pm8xxx-vib - fix handling of separate enable register
  Input: keyspan-remote - fix control-message timeouts
  Input: max77650-onkey - add of_match table
  Input: rmi_f54 - read from FIFO in 32 byte blocks
  Revert "Input: synaptics-rmi4 - don't increment rmiaddr for SMBus transfers"
  Input: sur40 - fix interface sanity checks
  Input: gtco - drop redundant variable reinit
  Input: gtco - fix extra-descriptor debug message
  Input: gtco - fix endpoint sanity check
  Input: aiptek - use descriptors of current altsetting
  Input: aiptek - fix endpoint sanity check
  Input: pegasus_notetaker - fix endpoint sanity check
  Input: sun4i-ts - add a check for devm_thermal_zone_of_sensor_register
  Input: evdev - convert kzalloc()/vzalloc() to kvzalloc()
