As I previously said you need to follow the patch submission process in
SubmittingPatches.  Here you need to:

 - Sign off your patch.  Without this your patch cannot be applied.
 - Send the patches to the maintainers (not just one of them) and the
   list.

You should also make an effort to use subject lines for your patch that
match up with what the rest of the subsystem is doing.
