Just stumbled over this lincense header: Generally drm is mit/gpl dual
lincensed. The important part for me is the drm core, but due to all the
refactoring we tend to do and code extraction from drivers those are
rather relevant imo, too. Was this just an oversight or are you still
working with your legap people on this?
