So i tested this now.

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

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.
