2e775f2d41ef ("drm/i915/display: update intel_dp_has_audio to support MST")
6297ee90f682 ("drm/i915/display: configure SDP split for DP-MST")
The division of changes here is not ideal, but I presume the goal was to
not do functional changes compared to intel_dp_mst_has_audio(). Which
may or may not be a good reason...
