Subject: [PATCH v3 07/16] hda: cs35l41: Put the device into safe mode for external boost
Date:   Tue, 8 Mar 2022 17:17:21 +0000
Message-ID: <20220308171730.454587-8-tanureal@opensource.cirrus.com>

To facilitate the configuration of external boost devices, put all
devices, with or without VSPK switch, into safe mode from the start.
That allows the following parts of the driver to handle all external
boost devices in the same way.
