Subject: [PATCH v1] ALSA: SOF: sof-pci-dev: Fix community key quirk detection
Date:   Fri, 20 Oct 2023 14:59:53 -0600
Message-ID: <20231020145953.v1.1.Iaf5702dc3f8af0fd2f81a22ba2da1a5e15b3604c@changeid>
MIME-Version: 1.0

Precedence: bulk

Some Chromebooks do not populate the product family DMI value resulting
in firmware load failures.

Add another quirk detection entry that looks for "Google" in the BIOS
version. Theoretically, PRODUCT_FAMILY could be replaced with
BIOS_VERSION, but it is left as a quirk to be conservative.
