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