Subject: net: ethernet: lpc_eth: use phydev from struct net_device
X-Git-Tag: v4.8-rc1~140^2~232

net: ethernet: lpc_eth: use phydev from struct net_device

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.
