4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Sakari Ailus <[email protected]> commit 41387a59c8fd55975c6a26cc12fc5c9ca61fcc0f upstream. There's a sanity check for the stream count remaining positive or zero on error path, but instead of performing the check on the traversed entity it is performed on the entity where traversal ends. Fix this.
