[PATCH] drm/nouveau: Fix regression by audio component transition
Since the commit 742db30c4ee6 ("drm/nouveau: Add HD-audio component
notifier support"), the nouveau driver notifies and pokes the HD-audio
HPD and ELD via audio component, but this seems broken. The culprit
is the naive assumption that crtc->index corresponds to the HDA pin.
Actually this rather corresponds to the MST dev_id (alias "pipe" in
the audio component framework)

[PATCH RESEND] drm/nouveau: Add HD-audio component notifier support
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

[PATCH 8/8] drm/nouveau/kms/nv50-: Fix locking for audio callbacks
Noticed that I wasn't paying close enough attention the last time I looked
at our audio callbacks, as I completely missed the fact that we were
figuring out which audio-enabled connector goes to each encoder by checking
it's state, but without grabbing any of the appropriate modesetting locks
to do so.
That being said however: trying to grab modesetting locks in our audio
callbacks would
