Merge tag 'gpio-fixes-for-v6.5-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio fixes from Bartosz Golaszewski:
- fix initial value handling for output-only pins in gpio-tps68470
- fix two resource leaks in gpio-mvebu
* tag 'gpio-fixes-for-v6.5-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux:
gpio: mvebu: fix irq domain leak
gpio: mvebu: Make use of devm_pwmchip_add
gpio: tps68470: Make tps68470_gpio_output() always set the initial value
