With x86_64_defconfig:
GCC thinks that in nfulnl_recv_config flags parameter is not inited but
it was under the same condition (nfula[NFULA_CFG_FLAGS] == true).
Suppress this warning:
net/netfilter/nfnetlink_log.c: In function ‘nfulnl_recv_config’:
net/netfilter/nfnetlink_log.c:320:14: warning: ‘flags’ may be used
uninitialized in this function [-Wmaybe-uninitialized]
inst->flags = flags;
