3.2.52-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Henrik Rydberg <[email protected]> commit 0fc86eca1b338d06ec500b34ef7def79c32b602b upstream. Some error paths do not set a result, leading to the (false) assumption that the value may be used uninitialized. Set results for those paths as well.
