As this patch was sent to you and you forward it you need to
testify that this is OK.
To do so follow the rules of the Developemnt Certificate of Origin
as can be found in SubmittingPatches.rst.

In other words - you need to add your Signed-off-by: xxx <mail>
to the patch.
In the end we want to be able to see the patch the patch has taken
reading the Signed-off-by: lines from top to bottom.

Please check other patches in this series for the same issue.
