Subject: [PATCH 30/48] net: dsa: mt7530: empty default case on
mt7530_setup_port5()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There're two code paths for setting up port 5:
mt7530_setup()
-> mt7530_setup_port5()
mt753x_phylink_mac_config()
-> mt753x_mac_config()
-> mt7530_mac_config()
-> mt7530_setup_port5()
On the first code path, priv->p5_intf_sel is either set to
P5_INTF_SEL_PHY_P0 or P5_INTF_SEL_PHY_P4 when mt7530_setup_port5() is run.
On the second code path, priv->p5_intf_sel is set to P5_INTF_SEL_GMAC5 when
mt7530_setup_port5() is run.
Empty the default case which will never run but is needed nonetheless to
handle all the remaining enumeration values.
