tbh, most if not all arm drivers are gpl only, and due to code sharing and
refactoring I'd say a lot of that has leaked all over drm. IANAL and all
that, but personally I believe that the entire idea of drm being MIT is
walking on ever thinner ice. And personally I'm not going to extend effort
to slow this down or prevent it outright, since I think all that code
sharing with arm folks is extremely beneficial for everyone. At least here
on Linux.
