phy: phy_ethtool_ksettings_set: Lock the PHY while changing settings
commit af1a02aa upstream. There is a race condition where the PHY state machine can change members of the phydev structure at the same time userspace requests a change via ethtool. To prevent this, have phy_ethtool_ksettings_set take the PHY lock. Fixes: 2d55173e ("phy: add generic function to support ksetting support") Reported-by:Walter Stoll <Walter.Stoll@duagon.com> Suggested-by:
