Enforcing this requirement has become a bit more strict with commit ef4c6270bf2867e2f8032e9614d1a8cfc6c71663 Author: Daniel Vetter Date: Thu Oct 15 09:36:25 2015 +0200 drm/gem: Check locking in drm_gem_object_unreference Cc: Dave Airlie Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1459330852-27668-4-git-send-email-daniel.vetter@ffwll.ch Link: http://patchwork.freedesktop.org/patch/msgid/1459330852-27668-5-git-send-email-daniel.vetter@ffwll.ch --- diff --git a/drivers/gpu/drm/qxl/qxl_fb.c b/drivers/gpu/drm/qxl/qxl_fb.c index 7136e521e6db..bb7ce07b788b 100644 --- a/drivers/gpu/drm/qxl/qxl_fb.c +++ b/drivers/gpu/drm/qxl/qxl_fb.c @@ -443,11 +443,11 @@ out_unref: } } if (fb && ret) { - drm_gem_object_unreference(gobj); + drm_gem_object_unreference_unlocked(gobj); drm_framebuffer_cleanup(fb); kfree(fb); } - drm_gem_object_unreference(gobj); + drm_gem_object_unreference_unlocked(gobj); return ret; }
