You can not add someone else's signed-off-by: line to a patch, please go
re-read Documentation/SubmittingPatches as to why.

And did Adam originally write this patch?  Or did you?  If Adam, please
set the authorship information properly.

Oh, and please spell out email addresses properly in signed-off-by
lines, it doesn't hide anything when you do that :)

Third time's a charm?
