Merge tag 'input-for-v6.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input fixes from Dmitry Torokhov:

 - a fix for Zinitix driver to not fail probing if the property enabling
   touch keys functionality is not defined. Support for touch keys was
   added in 6.12 merge window so this issue does not affect users of
   released kernels

 - a couple new vendor/device IDs in xpad driver to enable support for
   more hardware

* tag 'input-for-v6.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: zinitix - don't fail if linux,keycodes prop is absent
  Input: xpad - add support for MSI Claw A1M
  Input: xpad - add support for 8BitDo Ultimate 2C Wireless Controller
