From 2a62416dc67922458f809776d67138f0cc5544cd Mon Sep 17 00:00:00 2001 From: Philippe Reynes Date: Sat, 2 Jul 2016 14:06:14 +0200 Subject: [PATCH] net: ethernet: ixp4xx_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 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.
