Subject: [PATCH 7/8] net: bridge: fix sign bug
Date: Thu, 15 Jul 2010 22:47:33 +0400 [thread overview]
Message-ID: <1279219653-12791-1-git-send-email-segooon@gmail.com> (raw)
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.
