Yes, the problem is, it probably needs another 50 patches to remove
all the duplication. I have to question, is that really going to
happen? Are you going to keep working on this until every driver has
its duplicates removed?

It probably needs some tooling to help. Something which can decode the
object file, and tell you which ops structures are identical. That can
then guide you when editing all the PHY drivers.
