3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Frediano Ziglio <fziglio@xxxxxxxxxx>
commit 8451cc964c1d193b989c41a44e5e77109cc696f8 upstream.
If the function fails reference counter to the object is not decremented
causing leaks.
This is hard to spot as it happens only on very low memory situations.
