drm/vblank: Document drm_crtc_vblank_restore constraints
I got real badly confused when trying to review a fix from Ville for this. Let's try to document better what's required for this, and check the minimal settings at runtime - we can't check ofc that there's indeed no races in the driver callback. Also noticed that the drm_vblank_restore version is unused, so lets unexport that while at it. Reviewed-by: Ville Syrjälä <> Cc: Ville Syrjala <> Signed-off-by: Daniel Vetter <> Link:
