Hi Daniel,
This is the previous patch relevant to this discussion:

So before I refactored the code to leverage drm_minor, I kept my own
list of "known" drm_device inside the controller and have explicit
register and

This is the previous patch relevant to this discussion:
https://patchwork.freedesktop.org/patch/314343/

of "known" drm_device inside the controller and have explicit register and
unregister function to init per
