Subject: [PATCH] drm/i915/audio: Use BIOS provided value for RKL HDA link
Date: Mon, 6 Sep 2021 12:12:59 +0800 [thread overview]
Message-ID: <20210906041300.508458-1-kai.heng.feng@canonical.com> (raw)
Commit 989634fb49ad ("drm/i915/audio: set HDA link parameters in
driver") makes HDMI audio on Lenovo P350 disappear.
So in addition to TGL, extend the logic to RKL to use BIOS provided
value to fix the regression.
Fixes: 989634fb49ad ("drm/i915/audio: set HDA link parameters in driver")
