Merge tag 'gpio-fixes-for-v6.16-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio fixes from Bartosz Golaszewski:
- fix performance regression when setting values of multiple GPIO lines
at once
- make sure the GPIO OF xlate code doesn't end up passing an
uninitialized local variable to GPIO core
- update MAINTAINERS
* tag 'gpio-fixes-for-v6.16-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux:
MAINTAINERS: remove bouncing address for Nandor Han
gpio: of: initialize local variable passed to the .of_xlate() callback
gpiolib: fix performance regression when using gpio_chip_get_multiple()
