[PATCH 1/2] net: ethernet: octeon: use phydev from struct net_device

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
