I've replaced the v1 that has been applied for some time already with
this one, but please note that it still is not entirely clean.

Namely, if there are two S-o-b targs on a patch, 2 cases are possible:

(1) The person sending it is not its author and merely sends someone
else's work adding an S-o-b to document a "supply chain link".  In
this case, the From: header should point to the original author (it
can be added right before the changelog) and its value should match
the other S-o-b tag exactly.

(2) The person sending it is one of its authors.  In this case, a
Co-developed-by tag should be added to point to the other author and
its value should match the other S-o-b tag exactly.

I've assumed (2) and added "Co-developed-by: Sanket Goswami
<Sanket.Goswami@amd.com>" to the commit, but that's not something I
should be doing.

Thanks!

Thanks! That was a miss.

Co-developed-by: Sanket Goswami <Sanket.Goswami@amd.com> is the right tag.
