I've got a mild preference for handling quirk assignment in the DT
rather than in driver code, so I'd prefer to just push the original
patch to mmc-next as-is.  Does that sound okay?

(I think the argument that there isn't going to be any new hardware
with this problem is equally in favor of both methods.)

Thanks,

- Chris.
