Indeed, something's not right here.

CODEC_PROBE_RETRIES is defined conditionally

#if IS_ENABLED(CONFIG_SND_SOC_SOF_HDA_AUDIO_CODEC)
#define IDISP_VID_INTEL	0x80860000
#define CODEC_PROBE_RETRIES 3

but it's used unconditionally.

We could define this constant unconditionally as a quick fix, but this
compilation problem might expose a larger problem.

Kai, I wonder if this is code from lines 120 to 139 that we didn't
update when we moved to support HDMI with the generic HDaudio parts? I
don't see why we could even try to send a command on the bus is there's
no audio codec support?

hda_codec_use_common_hdmi should be the default assumption now, I don't
think we support the old solution, do we?
