Merge tag 'irqchip-fixes-6.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent
Pull irqchip fixes from Marc Zyngier:
- MIPS GIC fixes for issues that could result in either
loss of state in the interrupt controller, or a deadlock
- Workaround for Mediatek Chromebooks that only save/restore
partial state when turning the GIC redistributors off,
resulting if fireworks if Linux uses interrupt priorities
for pseudo-NMIs
- Fix the MBIGEN error handling on init
- Mark meson-gpio OF data structures as __maybe_unused,
avoiding compilation warnings on non-OF setups
