I had used drm-misc-next because the original focus was to clean up
drivers in gpu/drm/ - and then I just continued to use this wrong tree.
linux-next is indeed a good place to catch the latest and greatest - but
as I now have the URL for the backlight tree (thanks to Lee) I will use it here.
Will try to find time this weekend so we can land these.
