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.
