To be symmetric with the error unwind path of dsa_switch_setup(), call dsa_switch_unregister_notifier() after ds->ops->teardown. The implication is that ds->ops->teardown cannot emit cross-chip notifiers. For example, currently the dsa_tag_8021q_unregister() call from sja1105_teardown() does not propagate to the entire tree due to this reason. However I cannot find an actual issue caused by this, observed using code inspection.
