Merge tag 'input-for-v6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input fixes from Dmitry Torokhov:

 - a couple fixups for adp5589-keys driver

 - recently added driver for PixArt PS/2 touchpads is dropped
   temporarily because its detection routine is too greedy and
   mis-identifies devices from other vendors as PixArt devices

* tag 'input-for-v6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: adp5589-keys - fix adp5589_gpio_get_value()
  Input: adp5589-keys - fix NULL pointer dereference
  Revert "Input: Add driver for PixArt PS/2 touchpad"
