Merge tag 'irqchip-fixes-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent
Pull irqchip fixes from Marc Zyngier:
A small bunch of fixes from the irqchip department:
- Fix a couple of UAF on error paths (RZA1, GICv3 ITS)
- Fix iMX GPCv2 trigger setting
- Add missing of_node_put on error path in MBIGEN
- Add another bunch of /* fall-through */ to silence warnings
