I inlined the patch I used below. If I'm not mistaken, the maintainer is
Davej which is already in the Cc: list. I think it's exactly the same as
was submitted in http://lkml.org/lkml/2007/1/16/297 (I may have hand
copied it though, can't remember). The above link is more complete as it
contains the Signed-off-by and a description.
