[PATCH] ALSA: hda: cs35l56: Add ACPI device match tables

From: Simon Trimmer
Date: Thu Mar 28 2024 - 08:14:32 EST


Adding the ACPI HIDs to the match table triggers the cs35l56-hda modules
to be loaded on boot so that Serial Multi Instantiate can add the
devices to the bus and begin the driver init sequence.
