static int skl_hda_audio_probe(struct platform_device *pdev)
Recent fix for jack detection caused a regression on systems with HDA audio codec but no HDMI/DP audio via i915 graphics, leading to a kernel oops at device probe. On these systems, HDA bus instance lookup fails, as the first ASoC runtime of the card is connected to a dummy codec (as no HDMI codec is present).
