Subject: [PATCH 1/2] net: ethernet: sun4i-emac: use phydev from struct net_device
Date: Sat, 18 Jun 2016 15:15:39 +0200 [thread overview]
Message-ID: <1466255740-20999-1-git-send-email-tremyfr@gmail.com> (raw)
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.
