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.
