[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

[PATCH 1/2] nouveau/bl: Assign different names to interfaces
Currently, every backlight interface created by Nouveau uses the same name,
nv_backlight. This leads to a sysfs warning as it tries to create an already
existing folder. This patch adds a incremented number to the name, but keeps
the initial name as nv_backlight, to avoid possibly breaking userspace; the
second interface will be named nv_backlight1, and so on.

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