4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Boris Brezillon <[email protected]> commit 9a0e9802217291e54c4dd1fc5462f189a4be14ec upstream. When using uni-planar formats (like RGB), the scaling parameters are stored in plane 0, not plane 1. Fixes: fc04023fafec ("drm/vc4: Add support for YUV planes.")
