I think I made trivial changes according to the original patch. But
without reply from other people with Signed-off-by or Reviewed-by
(Casey, Kees, John), I'll remove them. I guess you don't want your
Reviewed-by to be kept, so I'll remove it, except if you want to review
this patch (or the modified part).
