Merge tag 'input-for-v6.1-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input fixes from Dmitry Torokhov:

 - a fix for 8042 to stop leaking platform device on unload

 - a fix for Goodix touchscreens on devices like Nanote UMPC-01 where we
   need to reset controller to load config from firmware

 - a workaround for Acer Switch to avoid interrupt storm from home and
   power buttons

 - a workaround for more ASUS ZenBook models to detect keyboard
   controller

 - a fix for iforce driver to properly handle communication errors

 - touchpad on HP Laptop 15-da3001TU switched to RMI mode

* tag 'input-for-v6.1-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: i8042 - fix leaking of platform device on module removal
  Input: i8042 - apply probe defer to more ASUS ZenBook models
  Input: soc_button_array - add Acer Switch V 10 to dmi_use_low_level_irq[]
  Input: soc_button_array - add use_low_level_irq module parameter
  Input: iforce - invert valid length check when fetching device IDs
  Input: goodix - try resetting the controller when no config is set
  dt-bindings: input: touchscreen: Add compatible for Goodix GT7986U chip
  Input: synaptics - switch touchpad on HP Laptop 15-da3001TU to RMI mode
