Merge tag 'input-for-v6.13-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:

 - support for NT36672A touchscreen added to novatek-nvt-ts driver

 - a change to ads7846 driver to prevent XPT2046 from locking up

 - a change switching platform input dirves back to using remove()
   method (from remove_new())

 - updates to a number of input drivers to use the new cleanup
   facilities (__free(...), guard(), and scoped-guard()) which ensure
   that the resources and locks are released properly and automatically

 - other assorted driver cleanups and fixes.
