I have two FEC interfaces. One i my main access interface, and the second is used by DSA to access switches. With your patches, the module Used by count is equal to the number of interfaces which are up. Without your patches, the count is always 0. When i try to remove the fec module, without your patches, but DSA still using the interface, i get the same kernel:unregister_netdevice: waiting for eth1 to become free. Usage count = 1 as with your patch. So this is not a regression.
