[ Upstream commit9c2c2e62df] commitf5e64032a7("net: phy: fix resume handling") changes the locking semantics for phy_resume() such that the caller now needs to hold the phy mutex. Not all call sites were adopted to this new semantic, resulting in warnings from the added WARN_ON(!mutex_is_locked(&phydev->lock)). Rather than change the semantics, add a __phy_resume() and restore the old behavior of phy_resume().
