   4 Subject: [PATCH 619/703] drm: vc4-firmware-kms: Remove incorrect overscan
   5  support.
   6
   7 The overscan support was required for the old mailbox API
   8 in order to match up the cursor and frame buffer planes.
   9 With the newer API directly talking to dispmanx there is no
  10 difference, therefore FKMS does not need to make any
  11 adjustments.
