Subject: [PATCH] ASoC: SOF: Intel: hda: Initialize HDA controller after i915 init
Git-commit: cc352735d49c9c25fd711795bee35d3d001ddffa
Patch-mainline: v5.4-rc1
References: git-fixes

On some platforms, sound card registration fails when a HDMI
monitor is not connected. This is caused by a recent commit
that switched the order in which the HDA controller and the
i915 are initialized. Initializing the i915 before initializing
the HDA controller fixes the problem.
