If you want to play the GPL card, you will note that the GPL requires modified versions of a work to carry prominent notices that they have been modified, including the date of any change.
A signoff by a maintainer does not imply that any modifications have been made, so I don't think that counts as "prominent".

In which case, the changelog should have been amended to state that it's a modification of Ben's original submission.

Linux convention is to add a signoff *and* a description of any changes to the original submission in square brackets.
