[PATCH 0/5] drm/nouveau: Backlight fixes and cleanup
This series fixes some issues with nouveau's backlight support that were
causing kernel panics on module reloads, specifically on systems with
nouveau handling the backlight of one of the displays.
While we're at it, let's cleanup nouveau_backlight.c as well

Next version of https://patchwork.freedesktop.org/series/48596/ . Added

that instead so we don't print the GMUX warning more then once.

[PATCH 0/2] drm/nouveau: Fix panic on nouveau unload.
If have a couple patches I found while looking at a panic

Unloading the nouveau module on my optimus notebook machine causes
the system to panic. This started occuring when moving from 4.4
to 4.14.
These patches make it such that the system does not panic
when unloading the module.
4.14 also requires commit 34112bf4935d ("drm/nouveau/fbcon:
