Subject: net: ethernet: ti: cpmac: use phydev from struct net_device
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b401a9bce7f3e73ebbe10639e0986f7f3b01e5ca;p=openwrt%2Fstaging%2Fblogic.git

net: ethernet: ti: cpmac: 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.
