I would let Maulik comment more, but as far as I can tell the function has been ignoring the return value of irq_set_irq_wake() for much longer. Presumably one could logically say: Fixes: 6aced33f4974 ("pinctrl: msm: drop wake_irqs bitmap") ...though when you get past the commit that Maulik tagged you need a backport rather than a straight cherry-pick. That would make me believe that there is no real hurry to land the fix here. -Doug
