Imo fixing the regression isn't the job of the display side, since display
isn't the one that broke the reset contract. Well apart from not syncing
with pending non-blocking atomic modeset commits, which we could fix
easily by dropping DRIVER_ATOMIC from gen2-4. But I'm still trying to
figure out why Chris thinks this isn't a gem regression ...
