Yeah, it has slightly different Version string in your case.

Since patchwork (*) still didn't catch your patch you need to resend
with all maintainers and mailing lists included like Darren suggested.

(*) patchwork is a database which is tracking patches and patch series
that are communicated thru mailing lists. It makes maintainer's life
easier and allow to keep a trail of what has been done and when.
