[PATCH 1/2] drm/nouveau: Disable atomic support on a per-device basis
...ssuming that wouldn't have any unintended side-effects of course
dri/*/state only works with atomic drivers. There's no explicit state
with legacy drivers at all, it's all just implicit in hw and some
random driver structures.
We should make sure though that the debugfs stuff looks at
drm_drv_uses_atomic_modsetting(), and not DRIVER_ATOMIC. Former is
about the internals (i915 is internally atomic everywhere), latter
about the uapi (some old platforms aren't properly validated for full
atomic features, hence why it's disabled).

[PATCH 1/2] drm/nouveau: Disable atomic support on a per-device basis
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
We now have per-device driver_features, so let's use that
to disable atomic only for pre-nv50.
