One thing I noticed, the original patch [0] had a Signed-off from
Dominik already and you should keep that as he is the author, and then
add your Signed-off below that, as you are the submitter,

So it would look like:

Signed-off-by: Dominik Behr <dbehr@xxxxxxxxxxxx>
Signed-off-by: Mark Yao <mark.yao@xxxxxxxxxxxxxx>


That may not need a repost, but should probably be corrected when applying
the patch.
