Merge tag 'input-for-v6.11-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:

 - streamlined logic in input core for handling normal input handlers vs
   input filters

 - updates to input drivers to allocate memory with sizeof(*pointer)
   instead of sizeof(type)

 - change to ads7846 touchscreen driver to use hsync GPIO instead of
   requiring platform data with special method (which is not compatible
   with boards using device tree)

 - update to adc-joystick driver to handle inverted axes

 - cleanups in various drivers switching them to use the new "guard" and
   "__free()" facilities

 - changes to several drivers (adxl34x, atmel_mxt_ts, ati-remote2,
   omap-keypad, yealink) to stop creating driver-specific device
   attributes manually and use driver core facilities for this

 - update to Cypress PS/2 protocol driver to properly handle errors from
   the PS/2 transport as well as other cleanups

 - update to edt-ft5x06 driver to support ft5426 variant

 - update to ektf2127 driver to support ektf2232 variant

 - update to exc3000 driver to support EXC81W32 variant

 - update to imagis driver to support IST3038 variant

 - other assorted driver cleanups.
