Commitd50ccc2d39("tipc: add 128-bit node identifier") declared but never implemented tipc_node_id2hash(). Also commit5c216e1d28("tipc: Allow run-time alteration of default link settings") never implemented tipc_media_set_priority() and tipc_media_set_window(), commitcad2929dc4("tipc: update a binding service via broadcast") only declared tipc_named_bcast(). Since commitbe07f05639("tipc: simplify the finalize work queue") tipc_sched_net_finalize() is removed and declaration is unused.
