Merge tag 'pinctrl-v6.15-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control fixes from Linus Walleij:
"This deals with a crash in the Qualcomm pin controller GPIO
parts when using hogs.
The first patch to gpiolib makes gpiochip_line_is_valid()
NULL-tolerant.
The second patch fixes the actual problem"
* tag 'pinctrl-v6.15-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:
pinctrl: qcom: switch to devm_register_sys_off_handler()
gpiolib: don't crash on enabling GPIO HOG pins
