Sorry, but I have to ask, why a dual license here?  You are only linking
to GPL-2.0-only code, so why the different license?  Especially if you
used the GPL-2.0-only code to "translate" from.

If you REALLY REALLY want to use a dual license, please get your
lawyers to document why this is needed and put it in the changelog for
the next time you submit this series when adding files with dual
licenses so I don't have to ask again :)

thanks,
