If anyone has any objections, please let me know. ------------------ From: Nicholas Mc Guire [ Upstream commit 3dc6ddfedc2818eaaa36842fbb049191e0c5e50f ] The call to of_get_next_child() returns a node pointer with refcount incremented thus it must be explicitly decremented here in the error path and after the last usage.
