Potential issue with f5e64032a799 "net: phy: fix resume handling"

[Heiner Kallweit]

This commit forces callers of phy_resume() and phy_suspend() to hold
mutex phydev->lock. This was done for calls to phy_resume() and
phy_suspend() in phylib, however there are more callers in network
drivers. I'd assume that these other calls issue a warning now
because of the lock not being held.
So is there something I miss or would this have to be fixed?
