Suggest you to use below flow for sending patch:

- git format HEAD~1: generate patch
- ./scripts/checkpatch.pl xxxx.patch: check patch format
- git send-email xxxx.patch: use git to send patch so avoid any
  unexpected characters in the mail

P.s. Marc has a good presentation [1] for upstreaming patches, you
could check page 16 for how to use the git tool.
