[ Upstream commit fb07b8f83441febeb0daf199b5f18c6de9bbab03 ]
The hierarchy of PCH PIC, PCH PCI MSI and EIONTC is as following:
PCH PIC ------->| |---->EIOINTC PCH PCI MSI --->|
so the irq_data list of irq_desc for IRQs on PCH PIC and PCH PCI MSI is like this:
irq_desc->irq_data(domain: PCH PIC)->parent_data(domain: EIOINTC) irq_desc->irq_data(domain: PCH PCI MSI)->parent_data(domain: EIOINTC)
In eiointc_resume(), the irq_data passed into eiointc_set_irq_affinity() should be matched to EIOINTC domain instead of PCH PIC or PCH PCI MSI domain, so fix it.
Fixes: a90335c2dfb4 ("irqchip/loongson-eiointc: Add suspend/resume support")
