Commits must be referenced with 12 characters of significance in the
SHA1-ID and appear in an appropriately formed "Fixes: " tag right
before the signoffs.

As-per Documentation/SubmittingPatches.

It also doesn't look so good how you lack a space between the SHA1-ID
and the commit message header text reference.
