Looks sane to me, though I've never touched this driver. Reviewed-by: Brian Norris <[email protected]> BTW just a comment from an outsider here, the "can sleep" terminology seems a bit misleading here. Just IMO of course, but saying something "can sleep" sounds like a permissive statement, when actually it's a restrictive statement being made by the driver (which is in this case unnecessarily restrictive). The "might sleep" terminology used in one other place would (again IMO) better communicate what I think is intended here. Though this problem is most likely result of mindless copy-and-paste, it's possible that the terminology made it easier to gloss over. Or I could just be blowing smoke.
