Subject: [PATCH] ALSA: hda: cs35l41: Put the device into safe mode for external boost
Git-commit: f04bb4cae18b8eb7e7e7bc35a8e07f1f26bbb919
Patch-mainline: v5.19-rc1
References: bsc#1203699
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.
