Next version of https://patchwork.freedesktop.org/series/48596/ . Made some important changes to the refactoring patch, but everything else is the same. Lyude Paul (5): drm/nouveau: Check backlight IDs are >= 0, not > 0 drm/nouveau: Move backlight device into nouveau_connector drm/nouveau: s/nouveau_backlight_exit/nouveau_backlight_fini/ drm/nouveau: Cleanup indenting in

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 Lyude Paul (5): drm/nouveau: Check backlight IDs are >= 0, not > 0 drm/nouveau: Move backlight device into

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:
