[RFC PATCH v2 3/3] ACPI / scan: Create platform device for INT3515 ACPI nodes

From: Lucas Tanure
Date: Wed Oct 20 2021 - 05:00:52 EST


The ACPI device with CLSA0100 is a sound card with multiple
instances of CS35L41.

We add an ID to the I2C multi instantiate list to enumerate
all I2C slaves correctly.
