From 10414444cb8a8ee8893e00390b7cf40502e28352 Mon Sep 17 00:00:00 2001 From: Herbert Xu <herbert@gondor.apana.org.au> Date: Thu, 18 Mar 2010 23:00:22 +0000 Subject: [PATCH] ipv6: Remove redundant dst NULL check in ip6_dst_check As the only path leading to ip6_dst_check makes an indirect call through dst->ops, dst cannot be NULL in ip6_dst_check. This patch removes this check in case it misleads people who come across this code. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
