Reviewed-by: Douglas Anderson <[email protected]> I'll plan to apply this patch next week unless there are any comments. Given that it's just adding a quirk, I'm also happy to apply it soonner (or for someone else to apply it) if people think that's OK. :-) NOTE: in general if someone is involved in the discussion of a previous versoin, it's good to CC them on newer versions. I've added Jani back to the CC list here. -Doug
