Subject: [PATCH 1/3] ASoC: codecs: pm4125: 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: 8ad529484937 ("ASoC: codecs: add new pm4125 audio codec driver")
