Merge tag 'gpio-fixes-for-v5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio fixes from Bartosz Golaszewski: - use the correct register for regcache sync in gpio-pca953x - remove unused and potentially harmful code from gpio-adp5588 - MAINTAINERS update * tag 'gpio-fixes-for-v5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: gpio: adp5588: Remove support for platform setup and teardown callbacks gpio: pca953x: use the correct register address to do regcache sync MAINTAINERS: Update Intel GPIO (PMIC and PCH) to Supported MAINTAINERS: Update GPIO ACPI library to Supported
