-Subject: [PATCH] drm/vc4: Drop planes that are completely off-screen
-
-It is permitted for a plane to be configured such that none
-of it is on-screen via either negative dest rectangle X,Y
-offset, or just an offset that is greater than the crtc
-dimensions.
-
-These planes were resized via drm_atomic_helper_check_plane_state
-such that the source rectangle had a zero width or height, but
-they still created a dlist entry even though they contributed
-no pixels. In the case of vc6_plane_mode_set, that it could result
-in negative values being written into registers, which caused
-incorrect behaviour.
-
-Drop planes that result in a source width or height of 0 pixels
-to avoid the incorrect rendering.
