Not sure I'll have time to go back and review the series, but one
thing that caught my eye as this flashed through my inbox is that I
think all of these "shouting" are deprecated. It's even officially
documented now as of commit d2f0a8afc1be ("UPSTREAM: drm/print: Add
deprecation notes to DRM_...() functions").
Agreed. But not the DRM_INFO too.
