From 1e8b73896f15b5a83dfb18924169f23450bae064 Mon Sep 17 00:00:00 2001 From: Philippe Reynes Date: Fri, 15 Jul 2016 12:05:11 +0200 Subject: [PATCH] net: ethernet: amd: au1000_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. Signed-off-by: Philippe Reynes Signed-off-by: David S.
