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

From: Philippe Reynes
Date: Tue Sep 20 2016 - 16:30:28 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.
