Pull irq fixes from Ingo Molnar:
"Misc irqchip fixes: LoongArch driver fixes and a Hyper-V IOMMU fix"
* tag 'irq-urgent-2022-08-21' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
irqchip/loongson-liointc: Fix an error handling path in liointc_init()
irqchip/loongarch: Fix irq_domain_alloc_fwnode() abuse
irqchip/loongson-pch-pic: Move find_pch_pic() into CONFIG_ACPI
irqchip/loongson-eiointc: Fix a build warning
irqchip/loongson-eiointc: Fix irq affinity setting
iommu/hyper-v: Use helper instead of directly accessing affinity
