From b18c25afabf80972b32a3918f6d7f16fbd54b18f Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Mon, 8 Apr 2024 06:22:06 +0000 Subject: [PATCH] soundwire: intel_ace2x: use legacy formula for intel_alh_id Starting with Lunar Lake, the notion of ALH is mostly irrelevant, since the HDaudio DMAs are used. However the firmware still relies on an 'ALH gateway' with a 'node_id' based on the same formula. This patch in isolation has no functional impact, it's only when the ASoC parts use it that we will see a changed behavior.
