Pull gpio fixes from Bartosz Golaszewski:

 - fix a regression in GPIO ACPI on HP ElitePad 1000 G2 where the
   gpio_set_debounce_timeout() now returns a fatal error if the specific
   debounce period is not supported by the driver instead of just
   emitting a warning

 - fix return values of irq_mask/unmask() callbacks in gpio-uniphier

 - fix hwirq calculation in gpio-aspeed-sgpio

 - fix two issues in gpio-rockchip: only make the extended debounce
   support available for v2 and remove a redundant BIT() usage

* tag 'gpio-fixes-for-v5.15-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux:
  gpio/rockchip: fix get_direction value handling
  gpio/rockchip: extended debounce support is only available on v2
  gpio: gpio-aspeed-sgpio: Fix wrong hwirq in irq handler.
  gpio: uniphier: Fix void functions to remove return value
  gpiolib: acpi: Make set-debounce-timeout failures non fatal
