From mboxrd@z Thu Jan 1 00:00:00 1970 From: tremyfr@gmail.com (Philippe Reynes) Date: Thu, 14 Jul 2016 19:45:57 +0200 Subject: [PATCH 1/2] net: ethernet: xilinx: axienet: use phydev from struct net_device Message-ID: <1468518358-28735-1-git-send-email-tremyfr@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
