From bd408b33363035275403cfaadf2683d8c8e22dd7 Mon Sep 17 00:00:00 2001 From: Johannes Berg <johannes.berg@intel.com> Date: Fri, 29 Jun 2012 14:24:12 +0200 Subject: [PATCH] iwlwifi: remove unneeded NULL check There's no need to check trans for non-null here as it has already been checked in the caller. This fixes an smatch warning that we check after having dereferenced it.
