Summary
In the Linux kernel, the following vulnerability has been resolved: powerpc/spufs: Fix refcount leak in spufs_init_isolated_loader of_find_node_by_path() returns remote device nodepointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak.
