Next version of https://patchwork.freedesktop.org/series/48596/ . Made some important changes to the refactoring patch, but everything else is the same.

Next version of https://patchwork.freedesktop.org/series/48596/ . Added NV_INFO_ONCE and made "Move backlight device into nouveau_connector" use that instead so we don't print the GMUX warning more then once. Lyude Paul (5): drm/nouveau: Add NV_PRINTK_ONCE and variants drm/nouveau: Move backlight device into nouveau_connector drm/nouveau:

Forgot to send 6 patches instead of five since there's one new one now, whoops! No actual changes, next version of https://patchwork.freedesktop.org/series/48596/ Lyude Paul (6): drm/nouveau: Check backlight IDs are >= 0, not > 0 drm/nouveau: Add NV_PRINTK_ONCE and variants drm/nouveau: Move backlight device into nouveau_connector drm/nouveau:

Refactor for Ben, hopefully this time this should apply to his tree. Next version of https://patchwork.freedesktop.org/series/48596/ No changes otherwise.

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.

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:
