From f7e9e9feb09f833d03f5fc3f378083b4664bd374 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Nils=20Wallm=C3=A9nius?= Date: Wed, 14 Dec 2016 21:52:45 +0100 Subject: [PATCH] drm/amdgpu: Remove checking for atombios MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This is a left over from radeon, amdgpu doesn't support any non-atombios parts and amdgpu_device_init would bail if the check for atombios failed anyway.
