Subject: [PATCH v1] ALSA: hda: cs35l41: Override the _DSD for HP Zbook Fury 17 G9 to correct boost type
CS35L41 HDA driver requires ACPI to contain correct _DSD properties to
correctly configure the device. Whilst the HP Zbook Fury 17 G9 contains
valid _DSD properties, the boost type has been configured incorrectly
in the _DSD for this laptop. We can override these properties to fix
the boost type.
