net: bridge: fix build when IPv6 is disabled
The br_ip6_multicast_add_router() prototype is defined only when CONFIG_IPV6 is enabled, but the function is always referenced, so there is this build error with CONFIG_IPV6 not defined: net/bridge/br_multicast.c: In function ‘__br_multicast_enable_port’: net/bridge/br_multicast.c:1743:3: error: implicit declaration of function ‘br_ip6_multicast_add_router’; did you mean ‘br_ip4_multicast_add_router’? [-Werror=implicit-function-declaration] 1743 | br_ip6_multicast_add_router(br, port); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ | br_ip4_multicast_add_router net/bridge/br_multicast.c: At top level: net/bridge/br_multicast.c:2804:13: warning: conflicting types for ‘br_ip6_multicast_add_router’ 2804 | static void br_ip6_multicast_add_router(struct net_bridge *br, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ net/bridge/br_multicast.c:2804:13: error: static declaration of ‘br_ip6_multicast_add_router’ follows non-static declaration net/bridge/br_multicast.c:1743:3: note: previous implicit declaration of ‘br_ip6_multicast_add_router’ was here 1743 | br_ip6_multicast_add_router(br, port); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ Fix this build error by moving the definition out of the #ifdef.
