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

Pull input fixes from Dmitry Torokhov:
 "The main change is support for keyboards and touchpads found in 2015
  editions of Macbooks"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Revert "Input: zforce - don't overwrite the stack"
  Input: bcm5974 - add support for the 2015 Macbook Pro
  HID: apple: Add support for the 2015 Macbook Pro
  Input: bcm5974 - prepare for a new trackpad generation
  Input: synaptics - dump ext10 capabilities as well
