Right. Return is missing. I think I already fixed this - I guess I sent
wrong version... Sorry guys. I'll do v3 with only this return added -
and I'll send it to limited amount of recipients as I think most of you
guys may not be interested. Probably to Linus W, Geert and GPIO list
only. Let me know if you want to see the v3 (or other subsequent
patches)
