If the following call path returns an error from switchdev: nbp_vlan_flush -> __vlan_del -> __vlan_vid_del -> br_switchdev_port_vlan_del -> __vlan_group_free -> WARN_ON(!list_empty(&vg->vlan_list)); then the deletion of the net_bridge_vlan is silently halted, which will trigger the WARN_ON from __vlan_group_free(). The WARN_ON is rather unhelpful, because nothing about the source of the error is printed. Add a print to catch errors from __vlan_del. Signed-off-by:
