Mark had a few minor fixups he requested to the hi6210 i2s driver, so this patch proves them.
This patch adds a few extra error returns in cases that shouldn't happen, some style nits adding breaks to final default cases in switch statements, and tweaks to use devm_ variant of snd_soc_register_component.
