Hi! These are the backported versions of the eDP backlight fixes for i915 that Lenovo asked me to try getting into the Fedora kernel in time for beta. Note that these are pending upstream in intel's drm-intel-next-queued tree, and will make it into the kernel come next merge window. NOTE!!! While the exception for this was really only requested by Lenovo, there's a couple of additional laptop panels that got added upstream from Dell. Since the only extra work required to support them is just adding some IDs into a quirk list I figured it'd be harmless to include here as well. Feel free to drop them if you don't think including them is a good idea.
