I appreciate your efforts to get this done. From what I understand you rebased
the patches from the chromium kernel to mainline. So you should keep the
signed-off-by from the original author and just add you signed-off-by below that.
Also it would be nice to CC these persons so that they are aware of your effort.

Are you sure about this? I remember that Dan (CC'ed) told me that this is one of
the requirements to get upstream working.
Dan, can you clarify please?
