Generally Debian encourages maintainers to license their packaging
under the same license as upstream, so we can contribute back.
This applies to both GPL projects and non-GPL projects.

It might be a good idea to try and contact the patch authors for these
to ask them to relicense their patches and submit them upstream.

Agreed.

This license mismatch issue should apply to all licenses not just the
GPL. A good way to detect future instances of this issue and report
them to package maintainers would be if the lintian tool were to
automatically check for it. Please file a bug report against lintian
asking for license mismatch detection to be implemented.
