Subject: [PATCH 1/2] ALSA: hda/cs8409: Ensure Type Detection is only run on startup when necessary
Date:   Fri, 27 Aug 2021 12:02:51 +0100

From: Stefan Binding <sbinding@opensource.cirrus.com>

Type Detection should only be run after init and when the controls have been
built. There is no need to run it multiple times.
