The call of of_get_child_by_name() will cause refcount incremented
for leds, if it succeeds, it should call of_node_put() to decrease
it, fix it.

To be 100% correct, it should have a CC: stable@vger.kernel.org

https://www.kernel.org/doc/html/latest/process/maintainer-netdev.html#stable-tree

But it will probably be O.K. with it missing.
