4 Subject: [PATCH 11/30] net: dsa: mt7530: do not run mt7530_setup_port5() if
5 port 5 is disabled

10 There's no need to run all the code on mt7530_setup_port5() if port 5 is
11 disabled. The only case for calling mt7530_setup_port5() from
12 mt7530_setup() is when PHY muxing is enabled. That is because port 5 is not
13 defined as a port on the devicetree, therefore, it cannot be controlled by
14 phylink.
15
16 Because of this, run mt7530_setup_port5() if priv->p5_intf_sel is
17 P5_INTF_SEL_PHY_P0 or P5_INTF_SEL_PHY_P4. Remove the P5_DISABLED case from
18 mt7530_setup_port5().
19
20 Stop initialising the interface variable as the remaining cases will always
21 call mt7530_setup_port5() with it initialised.
