Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull 2nd round of input updates from Dmitry Torokhov: - update to Wacom driver to support wireless devices - update to Sentelci touchpad driver to support newer hardware - update to gpio-keys driver to support "interrupt-only" keys - fixups to earlier commits * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: wacom - check for allocation failure in probe() Input: tegra-kbc - allocate pdata before using it Input: amijoy - add missing platform check Input: wacom - wireless battery status Input: wacom - create inputs when wireless connect Input: wacom - wireless monitor framework Input: wacom - isolate input registration Input: sentelic - improve packet debugging information Input: sentelic - minor code cleanup Input: sentelic - enabling absolute coordinates output for newer hardware Input: sentelic - refactor code for upcoming new hardware support Input: gpio_keys - add support for interrupt only keys Input: gpio_keys - consolidate key destructor code Input: revert "gpio_keys - switch to using threaded IRQs" Input: gpio_keys - constify platform data Input: spear-keyboard - remove kbd_set_plat_data()
