Merge tag 'gpio-fixes-for-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio fixes from Bartosz Golaszewski: - fix an irq mapping leak in gpio-sim - associate the GPIO device's software node with the irq domain in gpio-sim * tag 'gpio-fixes-for-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: gpio: sim: pass the GPIO device's software node to irq domain gpio: sim: dispose of irq mappings before destroying the irq_sim domain
