Subject: [PATCH net-next v2 07/12] net: dsa: lantiq_gswip: Use dsa_is_cpu_port() in gswip_port_change_mtu()
From: Martin Blumenstingl <martin.blumenstingl@...glemail.com>
Make the check for the CPU port in gswip_port_change_mtu() consistent
with other areas of the driver by using dsa_is_cpu_port().
