From 4b4ceb9dbf6a549682edff9fc5f04c204da50ab9 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Sun, 1 May 2016 00:34:37 +0200 Subject: netfilter: conntrack: __nf_ct_l4proto_find() always returns valid pointer 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.
