From 57078338b2e4c07fb76bef23369cae0acfb1f7bc Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 18 Sep 2018 16:20:18 +1000 Subject: [PATCH] drm: fix drm_drv_uses_atomic_modeset on non modesetting drivers. vgem seems to oops on the intel CI due to the vgem debugfs init hitting this path now. Check if we have mode_config funcs before checking one.
