Revision 29a1c581a5d873046302aa22c4a05124c5faefab authored by Nicholas Kazlauskas on 06 September 2022, 13:47:24 UTC, committed by Alex Deucher on 21 September 2022, 21:30:50 UTC
[Why] This shouldn't trigger during tiled display hotplug/unplug but it does because one of the tiles can end up with a NULL plane state. This also doesn't guard against the hang that it was originally trying to resolve, and can instead cause DIO corruption due to OTG sync being lost. [How] This was reverted at one point out of DCN31 so revert it here too.
