I am still waiting for feedback from the core lib maintainers on this patch.
If I just get an ACK I can apply it to the GPIO tree, if noone else cares
I might just go in and apply it, but it feels slightly outside of my
jurisdiction.

Maybe people were just a bit stressed out around christmas?

What about looking at it now?
