What does it mean to say that you're "keeping" the Signed-off-by when that
signoff was made on a very different patch and/or some smaller patch that got
squashed in?  You only need to include other people's signoff if you're
passing the patch on under section (c) of the DCO.  In this case you can use
section (a), and just write a sentence in the changelog giving any appropriate
credit to others.
