Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input fixes from Dmitry Torokhov: - a fix for cm109 stomping on its own control URB if it tries to toggle buzzer immediately after userspace opens input device (found by syzcaller) - another fix for Raydium touchscreens that do not like splitting command transfers - quirks for i8042, soc_button_array, and goodix drivers to make them work better with certain hardware. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: goodix - add upside-down quirk for Teclast X98 Pro tablet Input: cm109 - do not stomp on control URB Input: i8042 - add Acer laptops to the i8042 reset list Input: cros_ec_keyb - send 'scancodes' in addition to key events Input: soc_button_array - add Lenovo Yoga Tablet2 1051L to the dmi_use_low_level_irq list Input: raydium_ts_i2c - do not split tx transactions
