Tentatively applied as 6.3 material, but it was unclear what the S-o-b
tags below mean, so I've dropped them.

If you are not the original author of the patch, you should add a From
line pointing to the original author to it and the corresponding S-o-b
tag along with your S-o-b.

If you have developed the patch in collaboration with someone, there
should be a Co-developed-by tag pointing to the other author along
with the corresponding S-o-b tag.

S-o-b alone is meaningful only if you are sending a patch from someone
else, for example as a code maintainer.

Thank Rafael.

To clarify: this patch was developed by Stuart Hayes. So there should be no need for that additional Signed-off-bys.

Sorry for the confusion...
