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

Pull input fixes from Dmitry Torokhov:

 - a fix for Synaptics touchpads in RMI4 mode failing to suspend/resume
   properly because I2C client devices are now being suspended and
   resumed asynchronously which changed the ordering

 - a change to make sure we do not set right and middle buttons
   capabilities on touchpads that are "buttonpads" (i.e. do not have
   separate physical buttons)

 - a change to zinitix touchscreen driver adding more compatible
   strings/IDs

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: psmouse - set up dependency between PS/2 and SMBus companions
  Input: zinitix - add new compatible strings
  Input: clear BTN_RIGHT/MIDDLE on buttonpads
