[PATCH 0/5] drm/nouveau: Backlight fixes and cleanup
This series fixes some issues with nouveau's backlight support that were

nouveau handling the backlight of one of the displays.
While we're at it, let's cleanup nouveau_backlight.c as well

[PATCH 0/2] drm/nouveau: Fix panic on nouveau unload.

These patches make it such that the system does not panic
when unloading the module.
4.14 also requires commit 34112bf4935d ("drm/nouveau/fbcon:
