drivers/gpu/drm/xlnx/xlnx_sdi.c:1311:1-23: WARNING: Function "for_each_child_of_node" should have of_node_put() before goto around lines 1325.
drivers/gpu/drm/xlnx/xlnx_sdi.c:1311:1-23: WARNING: Function "for_each_child_of_node" should have of_node_put() before goto around lines 1333.


Semantic patch information:
 False positives can be due to function calls within the for_each
 loop that may encapsulate an of_node_put.
