If cec_notifier_cec_adap_unregister() is called before cec_unregister_adapter() then everything is OK (and this is the case today). But if it is the other way around, then cec_notifier_unregister() is called first, and that doesn't set n->cec_adap to NULL. So if e.g. cec_notifier_set_phys_addr() is called after cec_notifier_unregister() but before cec_unregister_adapter() then n->cec_adap points to an unregistered and likely deleted cec adapter. So just set n->cec_adap->notifier and n->cec_adap to NULL for rubustness. Eventually cec_notifier_unregister will disappear and this will be simplified substantially.
