Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input updates from Dmitry Torokhov: - a new driver for SparkFun Qwiic Joystick - pm8941-pwrkey driver now supports PMK8350 - a bunch of assorted driver fixes * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (44 commits) Input: joydev - prevent use of not validated data in JSIOCSBTNMAP ioctl Input: hideep - fix the uninitialized use in hideep_nvm_unlock() Input: trackpoint - use kobj_to_dev() Input: atkbd - use kobj_to_dev() Input: tsc200x-core - use kobj_to_dev() Input: ims-pcu - use kobj_to_dev() Input: cros_ec_keyb - use kobj_to_dev() API dt-bindings: input: touchscreen: st1232: Convert to json-schema Input: i8042 - fix typos in comments Input: add SparkFun Qwiic Joystick driver dt-bindings: Add vendor prefix and bindings for Qwiic Joystick Input: cy8ctmg110_ts - switch to using gpiod API Input: cy8ctmg110_ts - switch to using managed resources Input: cy8ctmg110_ts - use endian helpers when converting data on wire Input: cy8ctmg110_ts - let I2C core configure wake interrupt Input: cy8ctmg110_ts - do not hardcode as wakeup source Input: cy8ctmg110_ts - do not hard code interrupt trigger Input: cy8ctmg110_ts - rely on platform code to supply interrupt Input: resistive-adc-touch - fix uninitialized variable 'press' Input: pm8941-pwrkey - add support for PMK8350 PON_HLOS PMIC peripheral ...
