Merge tag 'gpio-fixes-for-v6.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio fixes from Bartosz Golaszewski:

 - add a quirk to GPIO ACPI handling to ignore touchpad wakeups on GPD
   G1619-04

 - clear interrupt status bits (that may have been set before enabling
   the interrupts) after setting the interrupt type in gpio-eic-sprd

  gpio: eic-sprd: Clear interrupt after set the interrupt type
  gpiolib: acpi: Ignore touchpad wakeup on GPD G1619-04
