Subject: ASoC: SOF: Intel: unregister DMIC device on probe error
From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>
commit 5bb0ecddb2a7f638d65e457f3da9fa334c967b14 upstream.
We only unregister the platform device during the .remove operation,
but if the probe fails we will never reach this sequence.
