Subject: [B.A.T.M.A.N.] [PATCH 08/12] batman-adv: Remove unnecessary check for orig_ifinfo not NULL
Date: Wed,  3 Jun 2015 16:14:04 +0200	[thread overview]
Message-ID: <1433340848-1682-9-git-send-email-antonio@meshcoding.com> (raw)
In-Reply-To: <1433340848-1682-1-git-send-email-antonio@meshcoding.com>

From: Sven Eckelmann <sven@narfation.org>

orig_ifinfo is dereferenced multiple times in batadv_iv_ogm_update_seqnos
before the check for NULL is done. The function also exists at the
beginning when orig_ifinfo would have been NULL. This makes the check at
the end unnecessary and only confuses the reader/code analyzers.
