Cover letter [PATCH v2 0/2] Fix observed mst problems with StarTech hub
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
Changes since v1:
* Add appropriate tags: Fixes & Cc
* Change debug macro to use drm_dbg_kms() instead
