The kernel doc for gpio-aggregator configfs interface, which was recently added, states that users should not be able to create an aggregator with a name prefixed by "_sysfs" via configfs. However, it was found that this guard does not function as expected (thanks to Dan Carpenter for identifying and fixing the issue). Add a test case to verify the guard.
