From bb7ca747f8d6243b3943c5b133048652020f4a50 Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Tue, 22 Mar 2011 16:30:21 -0700 Subject: backlight: add backlight type There may be multiple ways of controlling the backlight on a given machine. Allow drivers to expose the type of interface they are providing, making it possible for userspace to make appropriate policy decisions.

The original patch change the return value for dmi_check_cb(): https://lkml.org/lkml/2010/7/2/88 But commit 80183a4b changed the return value for set_backlight_level.
