net-ipv6: Fix alleged compiler warning in ipv6_exthdrs_len()
It was reported that Commit 299603e8370a93dd5d8e8d800f0dff1ce2c53d36
("net-gro: Prepare GRO stack for the upcoming tunneling support")
triggered a compiler warning in ipv6_exthdrs_len():
net/ipv6/ip6_offload.c: In function ‘ipv6_gro_complete’:
net/ipv6/ip6_offload.c:178:24: warning: ‘optlen’ may be used uninitialized in this function [-Wmaybe-u
opth = (void *)opth + optlen;
^
net/ipv6/ip6_offload.c:164:22: note: ‘optlen’ was declared here
int len = 0, proto, optlen;
^
Note that there was no real bug here - optlen was never uninitialized
before use. (Was the version of gcc I used smarter to not complain?)
