[PATCH 1/2] net: ethernet: et131x: use phydev from struct net_device

From: Philippe Reynes
Date: Fri Jun 17 2016 - 17:32:32 EST


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.
