Subject: [PATCH net-next] tunnel: use the correct endian for some fields
Date: Thu, 15 Nov 2012 16:51:22 +0800 [thread overview]
Message-ID: <1352969482-29836-1-git-send-email-amwang@redhat.com> (raw)
Fengguang reported:
net/ipv6/ip6_tunnel.c:1571:33: sparse: incorrect type in assignment (different base types)
net/ipv6/ip6_tunnel.c:1571:33: expected restricted __be32 [usertype] flowinfo
net/ipv6/ip6_tunnel.c:1571:33: got unsigned int
for these fields, we need to use the correct endian wrapers.
