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

I don't see why not so can you please send a patch to add that? Thanks.


dummy_irq_chip" ( is down, but works)

(e.g. drivers/gpio/gpio-pcf857x.c)

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.
