You can add an S-o-B even when you don't make changes to indicate a
"chain of custody" for the patch. You are certifying that the patch is,
to the best of your knowledge, properly credited and licensed.

It's not required for you to add your /own/ S-o-B to every patch you
send, but it's not hurting anything here either.

At least, that was my understanding of it. I know as a maintainer I add
my S-o-B to everything that goes through my tree even if I don't modify
it just to signify where the patch has been and who has handled it.
