-Subject: [PATCH 345/454] drm/vc4: Check if plane requires background fill
-
-commit 3d67b68a6a3c2deb689c29759a20150c668c286e upstream.
-
-Considering a single plane only, we have to enable background color
-when the plane has an alpha format and could be blending from the
-background or when it doesn't cover the entire screen.
-
-Changes from v1:
- - Drop unrelated change
- - Move needs_bg_fill to plane state
