how about "gpio_chip_hwnum()" to somewhat match irqdomain convention?

Sure, matching existing interfaces is better. "git grep hwnum" does not seem 
to reveal much related to irqdomain though?

I've only lightly scanned this patch, but I like what I see. I would
keep going with it.

Fantastic then - I just wanted to make sure things were not completely broken 
from the beginning. Since you and Linus W. seem to approve this, I will flush 
what I have in my head and publish a proper series for review.

Thanks!
