Subject: linux-next: build warning after merge of the netfilter-next tree

Hi all,

After merging the netfilter-next tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

In file included from net/netfilter/ipvs/ip_vs_core.c:52:
net/netfilter/ipvs/ip_vs_core.c: In function 'ip_vs_in_icmp':
include/net/ip_vs.h:233:4: warning: 'outer_proto' may be used uninitialized in this function [-Wmaybe-uninitialized]
  233 |    printk(KERN_DEBUG pr_fmt(msg), ##__VA_ARGS__); \
      |    ^~~~~~
net/netfilter/ipvs/ip_vs_core.c:1666:8: note: 'outer_proto' was declared here
 1666 |  char *outer_proto;
      |        ^~~~~~~~~~~

Introduced by commit

  73348fed35d0 ("ipvs: optimize tunnel dumps for icmp errors")
