The only case for calling mt7530_setup_port5() from mt7530_setup() is when PHY muxing is enabled. That is because port 5 is not defined as a port on the devicetree, therefore, it cannot be controlled by phylink. Because of this, run mt7530_setup_port5() if priv->p5_intf_sel is P5_INTF_SEL_PHY_P0 or P5_INTF_SEL_PHY_P4. Remove the P5_DISABLED case from mt7530_setup_port5(). Stop initialising the interface variable as the remaining cases will always call mt7530_setup_port5() with it initialised.
