[ Upstream commit d3d239dcb8aae6d7b10642d292b404e57604f7ea ]
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:
