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

…/git/dtor/input

Pull input updates from Dmitry Torokhov:

 - a fixup for Goodix touchscreen driver allowing it to work on certain
   Cherry Trail devices

 - a fix for imbalanced enable/disable regulator in Elam touchpad driver
   that became apparent when used with Asus TF103C 2-in-1 dock

 - a couple new input keycodes used on newer keyboards

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  HID: add mapping for KEY_ALL_APPLICATIONS
  HID: add mapping for KEY_DICTATE
  Input: elan_i2c - fix regulator enable count imbalance after suspend/resume
  Input: elan_i2c - move regulator_[en|dis]able() out of elan_[en|dis]able_power()
  Input: goodix - workaround Cherry Trail devices with a bogus ACPI Interrupt() resource
  Input: goodix - use the new soc_intel_is_byt() helper
  Input: samsung-keypad - properly state IOMEM dependency
