Subject: net: eepro100: Pass device private data into mdiobus
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=39daab23768895c32b82e153c21a7955ae7dacb8;p=oweals%2Fu-boot.git

net: eepro100: Pass device private data into mdiobus

Instead of doing ethernet device lookup by name every time there
is an MDIO access, pass the driver private data via mdiobus priv
to the MDIO bus accessors.
