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.
