   4 Subject: [PATCH] drm/vc4: Remove UIF from the list of modifiers
   5  returned by format_mod_supported
   6
   7 FKMS was listing UIF in the supported modifiers from format_mod_supported
   8 when actually the pipeline doesn't support it. X was then choosing to
   9 use it, and that then failed to render.
  10
  11 Remove references to UIF.
