Color management properties are a bit of an odd use case because
they're not marked as atomic properties. Currently we're not updating
the non atomic values so the drm_crtc_state is out of sync with the
values stored in the crtc object.
v2: Update non atomic values only if commit succeeds (Bob Paauwe)
v3: Do not access crtc_state after commit, use crtc->state (Maarten
Lankhorst)
