Merge tag 'irqchip-fixes-6.0-2' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent
Pull more irqchip fixes for 6.0 from Marc Zyngier:
- A couple of configuration fixes for the recently merged Loongarch drivers
- A fix to avoid dynamic allocation of a cpumask which was causing issues
with PREEMPT_RT and the GICv3 ITS
- A tightening of an error check in the stm32 exti driver
