From e55a68aeb0f8b9c74b582b7a5e92b82988832bf8 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ar=C4=B1n=C3=A7=20=C3=9CNAL?= Date: Mon, 22 Jan 2024 08:35:58 +0300 Subject: [PATCH 11/30] net: dsa: mt7530: do not run mt7530_setup_port5() if port 5 is disabled MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There's no need to run all the code on mt7530_setup_port5() if port 5 is disabled. 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.
