Not all devices with ACPI and this combination of sound devices will have the required information provided via ACPI. Reintroduce the I2C device ID to restore sound functionality on on the Chromebook 'Samus' model.

My fault for getting out of the habit of trying -rc1 when it comes out and not spotting this sooner. I'm not 100% sure if this fix is correct for all cases as I'm only able to test my hardware here, and this does fix my laptop. --- sound/soc/codecs/rt5677.c | 1 + 1 file changed, 1 insertion(+)
