[PATCH 0/2] Fix observed mst problems with StarTech hub

[Wayne Lin <Wayne.Lin@amd.com>]

Use Startech 1to3 DP hub to do some mst hotplug tests and find some
light up issues.

1. ACT polling timeout:
   Which is due to we didn't update DPCD payload table but still try
   to send ACT and polling for "ACT Handled" bit
2. Not all monitors light up:
   Due to we wrongly set unavailable VCP ID for new streams

Wayne Lin (2):
  drm/dp_mst: Do not set proposed vcpi directly
  drm/dp_mst: Avoid to mess up payload table by ports in stale topology
