Just in case this hasn't been reported yet. In next-20210514:

$ git grep br_multicast_is_router
net/bridge/br_input.c:                      br_multicast_is_router(br, skb)) {
net/bridge/br_multicast.c:      is_router = br_multicast_is_router(br, NULL);
net/bridge/br_private.h:br_multicast_is_router(struct net_bridge *br, struct sk_buff *skb)
                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
net/bridge/br_private.h:static inline bool br_multicast_is_router(struct net_bridge *br)
                                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
