It seems there are 3 patches sent from Marvin Häuser and I suppose they're in one patch-set, right? Please follow the link below to send out patch-set for review.
https://github.com/tianocore/tianocore.github.io/wiki/Laszlo's-unkempt-git-guide-for-edk2-contributors-and-maintainers
For example, if there are 3 commits in one patch-set, then the subject of the commits looks like:
[PATCH 0/4] This is the cover letter
[PATCH 1/4] This is patch 1

Otherwise the reviewers are confused by the patches.

Thanks!
Xu, Min
