Merge tag 'gpio-fixes-for-v5.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio fixes from Bartosz Golaszewski:
"A bunch of fixes for the GPIO subsystem. We have two regressions in
the core code spotted right after the merge window, a series of fixes
for ACPI GPIO and a subsequent fix for a related regression in
gpio-pca953x + a minor tweak in .gitignore and a rework of handling of
the gpio-line-names to remedy a regression in stm32mp151.
Summary:
- fix two regressions in core GPIO subsystem code: one NULL-pointer
dereference and one list corruption
- read GPIO line names from fwnode instead of using the generic
device properties to fix a regression on stm32mp151
- fixes to ACPI GPIO and gpio-pca953x to handle a regression in IRQ
handling on Intel Galileo
- update .gitignore in GPIO selftests"
* tag 'gpio-fixes-for-v5.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux:

gpiolib: acpi: Allow to find GpioInt() resource by name and index
gpiolib: acpi: Add ACPI_GPIO_QUIRK_ABSOLUTE_NUMBER quirk
gpiolib: acpi: Add missing IRQF_ONESHOT
gpio: fix gpio-device list corruption
gpio: fix NULL-deref-on-deregistration regression
selftests: gpio: update .gitignore
