From: Ville Syrjälä <[email protected]> As only a subset of primary planes are FBC capable there's no need to waste fences on all of them. So let's skip the fence if the plane isn't even fbc capable.
In the future we might extend this to skip the fence even for FBC capable planes if the crtc and/or plane state isn't suitable for FBC.
