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.
