Subject: [PATCH v2] ALSA: hda: cs35l41: Clarify support for CSC3551 without _DSD Properties
Date: Mon, 15 Aug 2022 17:29:06 +0100	[thread overview]
Message-ID: <20220815162906.463108-1-sbinding@opensource.cirrus.com> (raw)

For devices which use HID CSC3551, correct ACPI _DSD properties are
required to be able support those systems.
Add error message to clarify this.
