commit22a3703af1upstream. An error path was introduced without including the required call to of_node_put() to decrement the node's refcount and avoid leaking memory. If the call to kzalloc() for 'mgmt' fails, the probe returns without decrementing the refcount. Use the automatic cleanup facility to fix the bug and protect the code against new error paths where the call to of_node_put() might be missing again.
