drm/vc4: Reset ->{x, y}_scaling[1] when dealing with uniplanar formatsdrm-misc-fixes-2018-07-27
This is needed to ensure ->is_unity is correct when the plane was previously configured to output a multi-planar format with scaling enabled, and is then being reconfigured to output a uniplanar format. Fixes: fc04023fafec ("drm/vc4: Add support for YUV planes.")
