From d3d239dcb8aae6d7b10642d292b404e57604f7ea Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Wed, 24 Jun 2020 09:00:44 +0200 Subject: [PATCH] net: ethernet: mvneta: Do not error out in non serdes modes In mvneta_config_interface() the RGMII modes are catched by the default case which is an error return. The RGMII modes are valid modes for the driver, so instead of returning an error add a break statement to return successfully. This avoids this warning for non comphy SoCs which use RGMII, like SolidRun Clearfog: WARNING: CPU: 0 PID: 268 at drivers/net/ethernet/marvell/mvneta.c:3512 mvneta_start_dev+0x220/0x23c Fixes: b4748553f53f ("net: ethernet: mvneta: Fix Serdes configuration for SoCs without comphy") Signed-off-by: Sascha Hauer Reviewed-by: Russell King Signed-off-by: David S.
