Fix this by adding a check for\nphy_dev before calling the tse_pcs_fix_mac_speed() function.\n\nAlso clean up the tse_pcs_fix_mac_speed function a bit. There is\nno need to check for splitter_base and sgmii_adapter_base\nbecause the driver will fail if these 2 variables are not\nderived from the device tree."
