Wysocki" Cc: Aaron Lu , Zhang Rui , linux-acpi@vger.kernel.org Hi All, I've long wanted to have a way for users to force native-backlight behavior as that makes debugging backlight problems a bit easier. And now a laptop has shown up which needs native backlight behavior for things to work, has a non win8 ready bios, and I cannot use a quirk in the vendor backlight driver as it implements both the acer-wmi and ideapad-laptop vendor interfaces and putting the same quirk in 2 places is just wrong. So I've finally written a small patch to allow forcing native-backlight behavior as well as a second patch using this to add a quirk for said laptop. For now this is just a RFC series as I'm waiting for confirmation from the user that this actually fixes things, but I wanted to get the discussion going beforehand in case anyone has any objections against the solution I've come up with. Regards, Hans
