Subject: [PATCH AUTOSEL 5.16 08/59] ASoC: SOF: Intel: match sdw version on link_slaves_found

From: Bard Liao <yung-chuan.liao@...ux.intel.com>

[ Upstream commit f67c0c0d3b9048d86ea6ae52e36a2b78c48f265d ]

Codecs with the same part id, manufacturer id and part id, but different
sdw version should be treated as different codecs. For example, rt711 and
rt711-sdca are different. So, we should match sdw version as well.
