   4 Subject: [PATCH] drm/connector: Create a helper to attach the
   5  hdr_output_metadata property
   6
   7 All the drivers that implement HDR output call pretty much the same
   8 function to initialise the hdr_output_metadata property, and while the
   9 creation of that property is in a helper, every driver uses the same
  10 code to attach it.
  11
  12 Provide a helper for it as well
