Created attachment 162191 [details] Intel i915 Backlight Patch With the new kernel the backlight stopped working we had a patch written by jan michael brummer, but the patch stopped working probably due to code changes can we get a new patch?

Similar to https://bugs.freedesktop.org/show_bug.cgi?id=85977 There's generally no support for out-of-tree code breakage. But since I couldn't find a feature request bug for T100 backlight, I'll leave this open for now.
This should be fixed upstream. Please file any new bug reports at the freedesktop.org bugzilla [1]. Thank you. [1] https://bugs.freedesktop.org/enter_bug.cgi?product=DRI&component=DRM/Intel
