Subject: [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 everything as far as I can tell. Note that I
don't have any DSC displays locally yet, so if someone from AMD could
sanity check this I would appreciate it ♥.
