I'm cooking up a patchset which makes phy_read_status() take the
lock. I don't see any external callers taking the lock, so all the
changes are internal to phylib.

The change is however made a bit more complex by phy_read_status()
being in a header file, not phy.c. I wounder if there is some build
dependencies, modules vs built in. So my first patch simply moves it
into phy.c no other change. I will push it to github and let 0-day
chew on it for a while and see if it finds any build failures.
