Subject: [RESEND PATCH 07/11] soundwire: generic_bandwidth_allocation: remove useless init
Date: Fri, 26 Mar 2021 17:15:10 +0800 [thread overview]
Message-ID: <20210326091514.20751-8-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 two possible null pointer dereferences, but
it's more like there are unnecessary initializations before walking
through a list.
