From 477d9f0ea6ef6c1501b32434dc06ce3fbbf9c200 Mon Sep 17 00:00:00 2001 From: Lukas Wunner Date: Thu, 21 Jan 2016 15:10:21 -0800 Subject: drm/radeon: Fix WARN_ON if DRM_DP_AUX_CHARDEV is enabled MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rafael Antognolli's new DRM_DP_AUX_CHARDEV feature causes a WARN_ON if drm_dp_aux->dev == drm_connector->kdev and drm_dp_aux_unregister() is called after drm_connector_unregister(). radeon is the only driver affected by this besides i915. (amdgpu calls drm_dp_aux_unregister() before drm_connector_unregister().)
