[bug report] powerpc/fsl_rio: Missing of_node_put() calls in fsl_rio_setup()

[Markus Elfring]

Hello,

Another script for the semantic patch language (Coocinelle software) pointed
details out also according to the implementation of the function “fsl_rio_setup”
for further development considerations.

* I got the impression then that the function “of_node_put” should be called
  in more cases here.

* How do you think about to avoid a bit of duplicate source code
  by another update step?

* Further implementation details can be improved.


Regards,
Markus
