This change looks correct, in that it just replaces code with other
equivalent code.

But looking at it, i started to wonder about locking. I don't see
phydev->lock held anywhere. But it does access members of phydev, in
particular speed and duplex. If the PHY state machine is running at
the same time, and phy_read_status() is called, those members can
contain invalid information.

So i think another patch is needed to add locking to these two
functions.

Otherwise:
