From: Philippe Reynes Date: Sat, 2 Jul 2016 23:14:20 +0000 (+0200) Subject: net: ethernet: smsc: smsc911x: use phydev from struct net_device X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f788e322b730e42419ea2090fa3fdd99abcdc6fd;p=linux-beck.git net: ethernet: smsc: smsc911x: 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.
