From fc94d32dbf4f95353c89a51c1b3bef11c4ae30bd Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 27 Jul 2016 16:39:19 -0400 Subject: [PATCH] drm/radeon: drop confusing message about backlight control The message is harmless and confusing. On PX systems, there is one ATIF method, but potentially multiple GPUs leading to an error on the GPU with no backlight control.
