4 Subject: [PATCH] drm/connector: Create a helper to attach the
5 hdr_output_metadata property
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
12 Provide a helper for it as well
