From bd6e4c4a7060c7b994ccf808bf177c57ddde233e Mon Sep 17 00:00:00 2001 From: Cezary Rojewski Date: Mon, 26 Feb 2024 13:44:28 +0100 Subject: [PATCH] ALSA: hda: Skip i915 initialization on CNL/LKF-based platforms Commit 78f613ba1efb ("drm/i915: finish removal of CNL") and its friends removed support for i915 for all CNL-based platforms. HDAudio library, however, still treats such platforms as valid candidates for i915 binding. Update query mechanism to reflect changes made in drm tree. At the same time, i915 support for LKF-based platforms has not been provided so remove them from valid binding candidates.
