Merge tag 'gpio-fixes-for-v5.19-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio fixes from Bartosz Golaszewski: - make the irqchip immutable in gpio-realtek-otto - fix error code propagation in gpio-winbond - fix device removing in gpio-grgpio - fix a typo in gpio-mxs which indicates the driver is for a different model - documentation fixes - MAINTAINERS file updates * tag 'gpio-fixes-for-v5.19-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: gpio: mxs: Fix header comment gpio: Fix kernel-doc comments to nested union gpio: grgpio: Fix device removing gpio: winbond: Fix error code in winbond_gpio_get() gpio: realtek-otto: Make the irqchip immutable docs: driver-api: gpio: Fix filename mismatch MAINTAINERS: add include/dt-bindings/gpio to GPIO SUBSYSTEM
