When I first wrote this code, I had a lot of trouble getting the PHY to 
re-probe when the driver was unloaded and reloaded, and it was because 
of some odd problems with get/put of of_nodes.

Since I know that you didn't test this driver on real hardware, I have 
to test these patches myself before I can ACK them.
