This lead to irq_set_irq_wake() return error -ENXIO. However from 'commit 4110b5cbb014 ("irqchip/gic-v3: Allow interrupt to be configured as wake-up sources")' GIC irqchip has IRQCHIP_SKIP_SET_WAKE flag. Use return value from irq_set_irq_wake() and irq_chip_set_wake_parent() instead of always returning success.
