Merge tag 'input-for-v5.19-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input fixes from Dmitry Torokhov:
- fix Goodix driver to properly behave on the Aya Neo Next
- some more sanity checks in usbtouchscreen driver
- a tweak in wm97xx driver in preparation for remove() to return void
- a clarification in input core regarding units of measurement for
resolution on touch events.
* tag 'input-for-v5.19-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: document the units for resolution of size axes
Input: goodix - call acpi_device_fix_up_power() in some cases
Input: wm97xx - make .remove() obviously always return 0
Input: usbtouchscreen - add driver_info sanity check
