Subject: [PATCH 0/2] drm/probe_helper, i915: Validate MST modes against PBN limits

Something we've been missing for a while with drivers that support MST
is being able to prune modes that can't be set due to bandwidth
limitations. So, let's go ahead and add that. This also adds a new hook
that was needed, mode_valid_ctx, so that we can grab additional locks as
needed when validating modes.

Lee Shawn C (1):
  drm/i915/mst: filter out the display mode exceed sink's capability

Lyude Paul (1):
  drm/probe_helper: Add drm_connector_helper_funcs.mode_valid_ctx
