From bb7a0bd600ac2e09a8747ef89e692a2967ed8c97 Mon Sep 17 00:00:00 2001 From: Kulikov Vasiliy Date: Thu, 15 Jul 2010 08:47:33 +0000 Subject: [PATCH] net: bridge: fix sign bug ipv6_skip_exthdr() can return error code that is below zero. 'offset' is unsigned, so it makes no sense. ipv6_skip_exthdr() returns 'int' so we can painlessly change type of offset to int.
