From 351c4dbe4fae44b747dd97114a5983ec23a49f24 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 13 Sep 2018 19:31:47 +0300 Subject: [PATCH] drm/amdgpu: Use per-device driver_features to disable atomic MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Disable atomic on a per-device basis instead of for all devices. Made possible by the new device.driver_features thing.
