Summary
In the Linux kernel, the following vulnerability has been resolved: powerpc/cell/axon_msi: Fix refcount leak in setup_msi_msg_address of_get_next_parent() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() in the error path to avoid refcount leak.
