You patch is line wrapped .. It means it might not be easy to apply it..
You need to tell your mailer that the patch is "preformatted" . In the
kernel tree look at "Documentation/email-clients.txt" for more
information.

(btw, since your using git anyway you might want to look into using
git-format-patch and git-send-email for submitting)
