   4 Subject: [PATCH 356/454] drm/vc4: Add missing formats to
   5  vc4_format_mod_supported().
   6
   7 Daniel's format_mod_supported() patch predated Dave's for NV21/61, and
   8 I didn't catch that when rebasing.  This is a problem since the
   9 formats are now getting validated before being passed to the driver's
  10 atomic hooks.
