net: dsa: fix preparation of a port STP update
Because of the default 0 value of ret in dsa_slave_port_attr_set, a driver may return -EOPNOTSUPP from the commit phase of a STP state, which triggers a WARN() from switchdev. This happened on a 6185 switch which does not support hardware bridging. Fixes: 3563606258cf ("switchdev: convert STP update to switchdev attr set") Reported-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S.
