[PATCH v2 1/2] net: ethernet: ethoc: use phydev from struct net_device

From: Philippe Reynes
Date: Fri Jul 15 2016 - 03:59:31 EST


The private structure contain a pointer to phydev, but the structure
net_device already contain such pointer. So we can remove the pointer
phy in the private structure, and update the driver to use the
one contained in struct net_device.

Changelog:
v2:
- remove the definition of phy in the ethoc private struct (thanks Tobias Klauser)
