Merge tag 'gpio-fixes-for-v6.14-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio fixes from Bartosz Golaszewski:
- fix interrupt support in gpio-pca953x
- fix configfs attribute locking in gpio-sim
- limit the visibility of the GPIO_GRGPIO Kconfig symbol to OF systems
only
- update MAINTAINERS
* tag 'gpio-fixes-for-v6.14-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux:
MAINTAINERS: Use my kernel.org address for ACPI GPIO work
gpio: GPIO_GRGPIO should depend on OF
gpio: sim: lock hog configfs items if present
gpio: pca953x: Improve interrupt support
