Patch applied for fixes with Vladimir's ACK.

Hm, I see that the ambition was to merge the new irqchip
driver and the new GPIO driver in the same merge window.
Sorry if I was being too lazy/picky/whatever about the patch(es)
I guess I didn't quite get the scope of this change. :(

I should say that as long as we can agree that the new code
makes the kernel as a whole a better place, I am happy to
merge it. Sometimes also I need to zoom out from the GPIO
and pin control subsystem(s) and see the big picture.

Yours,
Linus Walleij
