Subject: [patch] [media] cx231xxx: fix typo in saddr_len check
Date: Thu, 23 Dec 2010 22:38:53 +0300	[thread overview]
Message-ID: <20101223193853.GN1936@bicker> (raw)
In-Reply-To: <34B38BE41EDBA046A4AFBB591FA311320249B057C6@NBMBX01.bbnet.ad>

The original code compared "saddr_len" with zero twice in a nonsensical
way.  I asked the list, and Andy Walls and Sri Deevi say that the second
check should be if "saddr_len == 1".
