Merge branch 'phy-unbind-crash'
Florian Fainelli says:
====================
net: phy: Fix PHY unbind crash
This fixes crashes when the PHY driver is no longer bound to the device.
There is still a fair amount of work to be done to get the unbind -> bind
sequent to result in a functional state, but that will be net-next material.
These two problems existed for as long as PHYLIB as been around.
