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.
