Subject: [RESEND PATCH 06/11] soundwire: bus: remove useless initialization
Date: Fri, 26 Mar 2021 17:15:09 +0800	[thread overview]
Message-ID: <20210326091514.20751-7-yung-chuan.liao@linux.intel.com> (raw)
In-Reply-To: <20210326091514.20751-1-yung-chuan.liao@linux.intel.com>

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

Cppcheck complains about a possible null pointer dereference, but it's
more like there is an unnecessary initialization before walking
