From: kernel test robot <lkp(a)intel.com&gt; drivers/net/ethernet/microchip/sparx5/sparx5_main.c:633:1-33: WARNING: Function "for_each_available_child_of_node" should have of_node_put() before goto around lines 670. Semantic patch information: False positives can be due to function calls within the for_each loop that may encapsulate an of_node_put.
