From: Andrew Lunn <andrew@...n.ch>
To: Florian Fainelli <f.fainelli@...il.com>
Cc: netdev <netdev@...r.kernel.org>, Andrew Lunn <andrew@...n.ch>
Subject: [RFC PATCH net-next 03/24] phy: Use phy_read() instead of mdiobus_read()
Since we have a phydev, make use of it and the phy_read() function.
This will help with later refactoring.
Signed-off-by: Andrew Lunn <andrew@...n.ch>
