   4 Subject: [PATCH] drm: vc4: 0 is a valid value for pixel_order_hvs5, so
   5  fix conditionals
   6
   7 vc4_plane_mode_set for HVS5 was using pixel_order unless pixel_order_hvs5
   8 was non-zero, except 0 is a valid value for the pixel_order.
   9
  10 Specify pixel_order_hvs5 for all formats and remove the conditional.
