## Overview

In the Linux kernel, the following vulnerability has been resolved:

platform/x86: dell-sysman: Fix reference leak

If a duplicate attribute is found using kset_find_obj(),
a reference to that attribute is returned. This means
that we need to dispose it accordingly. Use kobject_put()
to dispose the duplicate attribute in such a case.

Compile-tested only.
