omap_plane_atomic_update() does WARN_ON() if dispc rejects the given plane config. Change that to dev_err() to lessen the possible spam.
To fix this correctly, the plane setup needs much more work by creating a check function for dispc setup, so that we could reliably check the config in atomic_check, instead of only noticing the problem when programming dispc.
