Subject[PATCH v2 0/4] drm/dp_mst: Fix bandwidth checking regressions from DSC patches
Date
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 bandwidth-check related as far as I
can tell (I found some other regressions unrelated to AMD's DSC patches
which I'll be sending out patches for shortly). Note that I don't have
any DSC displays locally yet, so if someone from AMD could sanity check
this I would appreciate it ♥.

redundant
