From a19a6ee6cad2b20292a774c2f56ba8039b0fac9c Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Wed, 17 Feb 2010 16:39:44 -0500 Subject: backlight: Allow properties to be passed at registration Values such as max_brightness should be set before backlights are registered, but the current API doesn't allow that. Add a parameter to backlight_device_register and update drivers to ensure that they set this correctly.
