From: Daniel Vetter <daniel.vetter@xxxxxxxx> This patch has been added to the 3.18 stable tree. If you have any objections, please let us know. =============== [ Upstream commit 72b9ff0612ad8fc969b910cd00ac16b57a1a9ba4 ] For drm_gem_object_unreference callers are required to hold dev->struct_mutex, which these paths don't. Enforcing this requirement has become a bit more strict with commit ef4c6270bf2867e2f8032e9614d1a8cfc6c71663 Author: Daniel Vetter <daniel.vetter@xxxxxxxx> Date: Thu Oct 15 09:36:25 2015 +0200 drm/gem: Check locking in drm_gem_object_unreference Cc: stable@xxxxxxxxxxxxxxx Signed-off-by: Daniel Vetter <daniel.vetter@xxxxxxxxx> Signed-off-by: Dave Airlie <airlied@xxxxxxxxxx> Signed-off-by: Sasha Levin <sasha.levin@xxxxxxxxxx> --- drivers/gpu/drm/udl/udl_fb.c | 2 +- drivers/gpu/drm/udl/udl_gem.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/udl/udl_fb.c b/drivers/gpu/drm/udl/udl_fb.c index 5fc16ce..cd8d183 100644 --- a/drivers/gpu/drm/udl/udl_fb.c +++ b/drivers/gpu/drm/udl/udl_fb.c @@ -546,7 +546,7 @@ static int udlfb_create(struct drm_fb_helper *helper, return ret; out_gfree: - drm_gem_object_unreference(&ufbdev->ufb.obj->base); + drm_gem_object_unreference_unlocked(&ufbdev->ufb.obj->base); out: return ret; } diff --git a/drivers/gpu/drm/udl/udl_gem.c b/drivers/gpu/drm/udl/udl_gem.c index 8044f5f..6de963b 100644 --- a/drivers/gpu/drm/udl/udl_gem.c +++ b/drivers/gpu/drm/udl/udl_gem.c @@ -51,7 +51,7 @@ udl_gem_create(struct drm_file *file, return ret; } - drm_gem_object_unreference(&obj->base); + drm_gem_object_unreference_unlocked(&obj->base); *handle_p = handle; return 0; } -- 2.5.0 -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
