Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input subsystem updates from Dmitry Torokhov: "Two new drivers for Elan hardware (for I2C touchpad and touchscreen found in several Chromebooks and other devices), a driver for Goodix touch panel, and small fixes to Cypress I2C trackpad and other input drivers. Also we switched to use __maybe_unused instead of gating suspend/ resume code with #ifdef guards to get better compile coverage" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (27 commits) Input: gpio_keys - fix warning regarding uninitialized 'button' variable Input: add support for Elan eKTH I2C touchscreens Input: gpio_keys - fix warning regarding uninitialized 'irq' variable Input: cyapa - use 'error' for error codes Input: cyapa - fix resuming the device Input: gpio_keys - add device tree support for interrupt only keys Input: amikbd - allocate temporary keymap buffer on the stack Input: amikbd - fix build if !CONFIG_HW_CONSOLE Input: lm8323 - missing error check in lm8323_set_disable() Input: initialize device counter variables with -1 Input: initialize input_no to -1 to avoid subtraction Input: i8042 - do not try to load on Intel NUC D54250WYK Input: atkbd - correct MSC_SCAN events for force_release keys Input: cyapa - switch to using managed resources Input: lifebook - use "static inline" instead of "inline" in lifebook.h Input: touchscreen - use __maybe_unused instead of ifdef around suspend/resume Input: mouse - use __maybe_unused instead of ifdef around suspend/resume Input: misc - use __maybe_unused instead of ifdef around suspend/resume Input: cap11xx - support for irq-active-high option Input: cap11xx - add support for various cap11xx devices ...
