+Subject: [PATCH] drm: vc4-firmware-kms: Remove incorrect overscan
+ support.
+
+The overscan support was required for the old mailbox API
+in order to match up the cursor and frame buffer planes.
+With the newer API directly talking to dispmanx there is no
+difference, therefore FKMS does not need to make any
+adjustments.
