Apparently due to copying from some older or converted driver, the sun8i_emac driver contains pointless wrapper functions to bridge between a legacy driver and the driver model.
Since sun8i_emac is (and always was) driver model only, there is no reason to have those confusing wrappers. Just remove them, and use the driver model prototypes directly.
