HI Michael,
The actual changes are fine.
A couple of comments on the patch format.

  *   It's good to include the repository and package name, in the subject line

[Repo Name: [Optional] Patch Version# #/total #] PackageName: <One line summary of the change>

  *   Commit message is missing the BugZilla reference.
  *   CC maintainers as part of the patch mail.
You can get more details on these guidelines here<https://github.com/tianocore/tianocore.github.io/wiki/EDK-II-Development-Process>.

Regards,
Sai
