Subject[PATCH v2 2/3] net: ethernet: fec: use phydev from struct net_device
Date
The private structure contain a pointer to phydev, but the structure
net_device already contain such pointer. So we can remove the pointer
phydev in the private structure, and update the driver to use the one
contained in struct net_device.
