Subject: [PATCH 2/3] ASoC: codecs: wcd937x: drop bogus container_of() error handling

The dev_to_sdw_dev() helper uses container_of() to return the containing
soundwire device structure of its pointer argument and will never return
NULL.

Fixes: 9be3ec196da4 ("ASoC: codecs: wcd937x: add wcd937x codec driver")
