dim doesn't require Link: tags yet for pull requests (because most drm
trees aren't managed by dim and so lack them). Until we change that,
with some doc patches and proper bikeshed on dri-devel I think it's
fine if gvt is missing them. At least from a drm.git pov.

What you guys want to do for drm-intel.git is entirely up to you.
