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 ♥.
