This patch adds the support for the notification of HD-audio hotplug via the already existing drm_audio_component framework. This allows us more reliable hotplug notification and ELD transfer without accessing HD-audio bus; it's more efficient, and more importantly, it works without waking up the runtime PM. The implementation is rather simplistic: nouveau driver provides the get_eld ops for HD-audio, an...
