The Certificate of Origin says:

        (b) The contribution is based upon previous work that, to the best
            of my knowledge, is covered under an appropriate open source
            license and I have the right under that license to submit that
            work with modifications, whether created in whole or in part
            by me, under the same open source license (unless I am
            permitted to submit under a different license), as indicated
            in the file; or

If a previous author has given a Signed-off-by then they've clearly 
indicated that their code is under an appropriate license and may be 
submitted to the kernel. If someone else then takes that code, modifies 
it and submits it then there's no obvious reason why we still need the 
original Signed-off-by. Giving credit to the original author is 
obviously appropriate, but I don't see why we need any more than that.
