Subject: [PATCH 08/11] soundwire: intel: remove useless readl
Date: Tue, 2 Mar 2021 17:11:19 +0800 [thread overview]
Message-ID: <20210302091122.13952-9-yung-chuan.liao@linux.intel.com> (raw)
In-Reply-To: <20210302091122.13952-1-yung-chuan.liao@linux.intel.com>
From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
Cppcheck complains:
drivers/soundwire/intel.c:564:15: style: Variable 'link_control' is
assigned a value that is never used. [unreadVariable]
link_control = intel_readl(shim, SDW_SHIM_LCTL);
This looks like a leftover from a previous version, remove.
