The port_mst_index parameter was reserved for future use, but
maintainers prefer to add it later when it is actually used.
[Note: this is an update patch to commit [51e1d83cab: drm/i915: Call
audio pin/ELD notify function] where I mistakenly applied the older
version. Jani and Daniel's review tags were to the latest version,
so I add them below, too -- tiwai]
