Subject: [PATCH 24/36] netfilter: conntrack: __nf_ct_l4proto_find() always returns valid pointer
Date: Mon, 9 May 2016 20:46:42 +0200 [thread overview]
Message-ID: <1462819614-5402-25-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1462819614-5402-1-git-send-email-pablo@netfilter.org>
Remove unnecessary check for non-nul pointer in destroy_conntrack()
given that __nf_ct_l4proto_find() returns the generic protocol tracker
if the protocol is not supported.
