dsa: slave: Don't reference NULL pointer during phy_disconnect When the phy is disconnected, the parent pointer to the netdev it was attached to is set to NULL. The code then tries to suspend the phy, but dsa_slave_fixed_link_update needs the parent pointer to determine which switch the phy is connected to. So it dereferenced a NULL pointer. Check for this condition. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
