Subject: [PATCH] drm/amd/display: Use plane->color_space for dpp if specified
Git-commit: a1e07ba89d49581471d64c48152dbe03b42bd025
Patch-mainline: v5.2-rc1
References: bsc#1111666
[Why]
The input color space for the plane was previously ignored even if it
was set.
If a limited range YUV format was given to DC then the
wrong color transformation matrix was being used since DC assumed that
it was full range instead.
[How]
Respect the given color_space format for the plane if it isn't
COLOR_SPACE_UNKNOWN. Otherwise, use the implicit default since DM
didn't specify.
