bridge: move maybe_deliver_addr() inside #ifdef
The only caller of this new function is inside of an #ifdef checking for CONFIG_BRIDGE_IGMP_SNOOPING, so we should move the implementation there too, in order to avoid this harmless warning: net/bridge/br_forward.c:177:13: error: 'maybe_deliver_addr' defined but not used [-Werror=unused-function] Fixes: 6db6f0eae605 ("bridge: multicast to unicast") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: David S. Miller <davem@davemloft.net>
