Subject: [PATCH 4/4] mac80211: remove useless tests for array
Date: Mon, 28 Oct 2013 15:08:24 +0100	[thread overview]
Message-ID: <1382969304-25611-4-git-send-email-johannes@sipsolutions.net> (raw)
In-Reply-To: <1382969304-25611-1-git-send-email-johannes@sipsolutions.net>

From: Johannes Berg <johannes.berg@intel.com>

Coverity points out that checking assoc_data->ie is
completely useless since it's an array in the struct
and can't be NULL - remove the useless checks.
