drm/radeon/kms: allow rendering while no colorbuffer is set on r300
Because hardware cannot disable all colorbuffers directly to do depth-only rendering, a user should: - disable reading from a colorbuffer in blending - disable fastfill - set the color channel mask to 0 to prevent writing to a colorbuffer Signed-off-by: Dave Airlie <airlied@redhat.com>
