Subject: [patch] [SCSI] pm80xx: remove unneeded NULL check
Date: Thu, 9 May 2013 15:48:13 +0300	[thread overview]
Message-ID: <20130509124813.GA5132@elgon.mountain> (raw)
In-Reply-To: <518b863d.vBepQb4eXhQYEt/W%fengguang.wu@intel.com>

Coccinelle complains about the inconsistent NULL checking on "t".  It
turns out the check isn't needed because we verified that "t" is
non-NULL at the start of the function.
