This one I don't agree with.

This can switch to ->dport_dev if you like. The reason for ->dport was
for symmetry with the ->uport of a 'struct cxl_port'. So if you change
this to ->dport_dev then also make the ->uport_dev change for symmetry.

Unlike a 'struct cxl_port' a 'struct cxl_dport' is not a device in its
own right which is what I see when I read dport->dev.

There is already other occurrences of dport_dev as an argument, so I
think that works here too.
