From 86bc5ed672eea892dce43e8be8b3de6e58c51d5e Mon Sep 17 00:00:00 2001 From: Philippe Reynes Date: Sat, 30 Jul 2016 16:14:43 +0200 Subject: [PATCH] net: ethernet: octeon: 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.
