From b4a1ed0cd18b771e4279b4eb9cf39b565560eea6 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Thu, 20 Dec 2018 19:13:07 +0100 Subject: fbdev: make FB_BACKLIGHT a tristate BACKLIGHT_CLASS_DEVICE is already tristate, but a dependency FB_BACKLIGHT prevents it from being built as a module. There doesn't seem to be any particularly good reason for this, so switch FB_BACKLIGHT over to tristate.
