Subject[PATCH 5.10 026/157] ASoC: SOF: Intel: unregister DMIC device on probe error
Date
From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

commit 5bb0ecddb2a7f638d65e457f3da9fa334c967b14 upstream.

We only unregister the platform device during the .remove operation,
but if the probe fails we will never reach this sequence.
