-Subject: [PATCH] kms/nv50-: Move 8BPC limit for MST into nv50_mstc_get_modes()
-
-This just limits the BPC for MST connectors to a maximum of 8 from
-nv50_mstc_get_modes(), instead of doing so during
-nv50_msto_atomic_check(). This doesn't introduce any functional changes
-yet (other then userspace now lying about the max bpc, but we can't
-support that yet anyway so meh). But, we'll need this in a moment so
-that we can share mode validation between SST and MST which will fix
-some real world issues.
