[PATCH 0/3] drm/dp_mst: Fix bandwidth checking regressions from DSC patches
AMD's patch series for adding DSC support to the MST helpers
unfortunately introduced a few regressions into the kernel that I didn't
get around to fixing until just now. I would have reverted the changes
earlier, but seeing as that would have reverted all of amd's DSC support
+ everything that was done on top of that I realllllly wanted to avoid
doing that.
Anyway, this should fix

This is the series I've been working on for a while now to get all of
the atomic DRM drivers in the tree to use the atomic MST helpers, and to
make the atomic MST helpers actually idempotent. Turns out it's a lot
more difficult to do that without also fixing how port and branch device
