Subject: [PATCH v2 5/7] ASoC: codecs: realtek-soundwire: ignore initial PARITY errors
Date: Tue,  8 Sep 2020 21:45:19 +0800	[thread overview]
Message-ID: <20200908134521.6781-6-yung-chuan.liao@linux.intel.com> (raw)
In-Reply-To: <20200908134521.6781-1-yung-chuan.liao@linux.intel.com>

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

The parity calculation is not reset on a Severe Reset, which leads to
misleading/harmless errors reported on startup. The addition of a
quirk helps filter out such errors while leaving the error checks on
in steady-state.
