Boris Brezillon c9e666af54 drm/vc4: ->x_scaling[1] should never be set to VC4_SCALING_NONE ... [ Upstream commit 0560054da5673b25d56bea6c57c8d069673af73b ] For the YUV conversion to work properly, ->x_scaling[1] should never be set to VC4_SCALING_NONE, but vc4_get_scaling_mode() might return VC4_SCALING_NONE if the horizontal scaling ratio exactly matches the horizontal subsampling factor. Add a test to turn VC4_SCALING_NONE into VC4_SCALING_PPF when that happens. The old ->x_scaling[0] adjustment is dropped as I couldn't find any mention to this constraint in the spec and it's proven to be unnecessary (I tested various multi-planar YUV formats with scaling disabled, and all of them worked fine without this adjustment). Fixes: fc04023faf ("drm/vc4: Add support for YUV planes.")
