Good, I'll just add your ack on the original patch. Both v2 and v2-or-later
are obviously fine and I don't care either way, I just didn't like the
discrepancy. The SPDX id is normally trumping the module-license tag so the
original patch feels like the lesser change. No need to stir the bowl...

Peter
