Yep, thanks for following up on this.

However, your submission (https://patchwork.ozlabs.org/patch/467377/)
format is not correct. Your email client corrupted the whitespace,
your Signed-off-by is missing, a proper commit description is missing
and which tree your patch is targeted at. I presume -net tree as it's
a fix.

You're best off sending this patch via git-send-email(1), see also
Documentation/SubmittingPatches from the kernel tree.

Taking a random example submission from patchwork, this is how the end
result could look like:

   https://patchwork.ozlabs.org/patch/466743/

Thus, if you just write a proper commit message in git and use
git-format-patch(1) and git-send-email(1), you should be all set. Hope
that helps.

Cheers,
Daniel
