From 31abbe34e0f07e8c92f68865cb1d6dde0fe1d52d Mon Sep 17 00:00:00 2001 From: Philippe Reynes Date: Thu, 14 Jul 2016 01:48:51 +0200 Subject: [PATCH] net: ethernet: ll_temac: 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 phy in the private structure, and update the driver to use the one contained in struct net_device. Signed-off-by: Philippe Reynes Signed-off-by: David S.
