Heiner Kallweit ddb826c2c9 lan743x: fix deadlock in lan743x_phy_link_status_change() 
Usage of phy_ethtool_get_link_ksettings() in the link status change
handler isn't needed, and in combination with the referenced change
it results in a deadlock. Simply remove the call and replace it with
direct access to phydev->speed. The duplex argument of
lan743x_phy_update_flowcontrol() isn't used and can be removed.

Fixes: c10a485c3d ("phy: phy_ethtool_ksettings_get: Lock the phy for consistency")
