Merge tag 'drm-i915-get-eld' of tiwai/sound into drm-intel-next-queued
Add get_eld audio component for i915/HD-audio Currently, the HDMI/DP audio status and ELD are notified and obtained via the hardware-level communication over HD-audio unsolicited event and verbs although the graphics driver holds the exactly same information. As we already have a notification via audio component, this is another step forward; namely, the audio driver may fetch directly the audio status and ELD via the new component op.
