[Intel-gfx] [PATCH v5] drm/i915: pass ELD to HDMI/DP audio driver

Hi Christopher,

What if you run it with

        export HAS_PCH_SPLIT=1
        intel_audio_dump

I also queued a patch for the tool. Note that if the above trick
failed to work, the applied patch won't help, too.

Thanks,
Fengguang
