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
