---8<------------------------------------------------------------ From: Daniel Vetter <[email protected]> commit 72b9ff0612ad8fc969b910cd00ac16b57a1a9ba4 upstream. 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 <[email protected]> Date: Thu Oct 15 09:36:25 2015 +0200 drm/gem: Check locking in drm_gem_object_unreference Signed-off-by: Daniel Vetter <[email protected]> Signed-off-by: Dave Airlie <[email protected]> Signed-off-by: Kamal Mostafa <[email protected]> --- 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 8cbcb45..169326f 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 2a0a784..d7528e0 100644 --- a/drivers/gpu/drm/udl/udl_gem.c +++ b/drivers/gpu/drm/udl/udl_gem.c @@ -52,7 +52,7 @@ 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; } -- 2.7.4
