X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ec4c4aa14720b284af8eadd2d65d5131519fc29f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git drm/i915: Calculate the sprite WM based on the source width instead of the destination width Using the destination width in the sprite WM calculations isn't correct. We should be using the source width. Note: This doesn't affect hsw since it does not support sprite scaling.
