This doesn't reflect the patch anymore. Something like this should be
closer to reality:

"We fail to perform an of_node_put() when of_address_to_resource()
fails, leading to a refcount leak.

Address this by moving the error handling path outside of the loop and
making it common to all failure modes."

With the commit message fixed:
