Good to see this was applied. Still, I think no_irq_chip should also be fixed, cfr. my patch "genirq: Set IRQCHIP_SKIP_SET_WAKE for no_irq_chip and dummy_irq_chip" (https://lkml.org/lkml/2015/1/12/506 is down, but https://patchwork.ozlabs.org/patch/427788/ works)

Please note the particular pfc857x.c case was fixed by commit b80eef95beb04760 ("gpio: pcf857x: Propagate wake-up setting to parent irq controller"), as that driver has other problems. Now it no longer uses dummy_irq_chip.
