commit 61a41097e4bd4bf5d4abf3b3b58d5bf0856ce144 upstream.
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) while the actual port number is given from the output ior id number.
This patch corrects the assignment of port and dev_id arguments in the audio component ops to recover from the HDMI/DP audio regression.
