Merge tag 'input-for-v6.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input fixes from Dmitry Torokhov:

 - a tweak to uinput interface to reject requests with abnormally large
   number of slots. 100 slots/contacts should be enough for real devices

 - support for FocalTech FT8201 added to the edt-ft5x06 driver

 - tweaks to i8042 to handle more devices that have issue with its
   emulation

 - Synaptics touchpad switched to native SMbus/RMI mode on HP Elitebook
   840 G2

 - other minor fixes
