From 56d5c34a94dfb652592ba654ea236fb133e3686b Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Tue, 16 Jun 2015 16:28:09 +0200 Subject: sony-laptop: Port to new backlight interface selection API Port the backlight selection logic to the new backlight interface selection API. This commit also removes various obsolete pr_xxx messages related to backlight interface selection. These are obsolete because they assume there is only a vendor or acpi backlight driver and no other choice. Also they are not necessary, if the user wants to know which backlight interfaces are registered a simple "ls /sys/class/backlight" suffices.
