Merge tag 'input-for-v6.7-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:

 - a number of input drivers has been converted to use facilities
   provided by the device core to instantiate driver-specific attributes
   instead of using devm_device_add_group() and similar APIs

 - platform input devices have been converted to use remove() callback
   returning void

 - a fix for use-after-free when tearing down a Synaptics RMI device

 - a few flexible arrays in input structures have been annotated with
   __counted_by to help hardening efforts

 - handling of vddio supply in cyttsp5 driver

 - other miscellaneous fixups
