From c499696e7901bda18385ac723b7bd27c3a4af624 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Fri, 10 Nov 2017 11:33:26 -0800 Subject: [PATCH] net: dsa: b53: Stop using dev->cpu_port incorrectly dev->cpu_port is the driver local information that should only be used to look up register offsets for a particular port, when they differ (e.g: IMP port override), but it should certainly not be used in place of the DSA configured CPU port. Since the DSA switch layer calls port_vlan_{add,del}() on the CPU port as well, we can remove the specific setting of the CPU port within port_vlan_{add,del}. Fixes: ff39c2d68679 ("net: dsa: b53: Add bridge support") Fixes: 967dd82ffc52 ("net: dsa: b53: Add support for Broadcom RoboSwitch") Signed-off-by: Florian Fainelli Reviewed-by: Andrew Lunn Signed-off-by: David S.
