Gentle ping on this one... but then I realized that linusw isn't CC'ed
on this patch directly, and I'm unsure of what the workflow is for
pinctrl. ./scripts/get_maintainer.pl shows he should have been in the CC
list ideally :)

Maybe send a v3 with the changelog dropped from the actual message (i.e.
follow Bjorn's advice), and make sure to include the folks
get_maintainer tells you to so this gets picked up (or maybe just saying
Linus' name will make him appear out of the woodworks if we're lucky):

I'm eager to get this fix in so I can describe a missing IRQ or two
wrt ethernet GPIOs and submit that without stating the dependency
on this fix! :)

Thanks,
Andrew
