Not sure if you were confused by the comment in the same way that I was.

The bridge hook is not impacted by this at all, since we can either pass
a void* or a struct net_bridge_port* to it. The br_port() helper
is used for all the places where we actually want to dereference
dev->br_port and access its contents.
