The call to of_find_node_by_name returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage.
Detected by coccinelle with the following warnings: ./arch/powerpc/platforms/83xx/km83xx.c:68:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 59, but without a corresponding object release within this function.
