This series releases the np device_node when it is no longer required by adding the missing calls to of_node_put() to make the fix compatible with all affected stable kernels. Then, the more robust approach via cleanup attribute is used to simplify the handling and prevent issues if the loop gets new execution paths.
These issues were found while analyzing the code, and the patches have been successfully compiled, but not tested on real hardware as I don't have access to it. Any volunteering for testing is always more than welcome.
