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
