4 Subject: [PATCH 0989/1085] drm/vc4: Enable bg_fill if there are no planes
5 enabled
6
7 The default was to have enable_bg_fill disabled and the first
8 plane set it if it wasn't opaque and covering the whole screen.
9 However that meant that if no planes were enabled, then the
10 background fill wasn't enabled, and would give a striped
11 output from the uninitialised output buffer.
12
13 Initialise it to enabled to avoid this.
