Yes that is what we should do _but_

I think we should tackle that in a different series.

As you said in another email, this series is getting very long and hard to review/prove is correct. This is why I was advocating keeping a check at the top of cm_add_one which verified all Ports supported the CM. This is the current logic today and is proven to work for the devices/use cases out there.

We can clean up the initialization code and implement support for individual ports in follow on patches.
