    [POWERPC] arch/powerpc/platforms/pseries: Add missing of_node_put · 842decbd
    Julia Lawall authored
    Of_get_parent and of_find_compatible_node do an of_node_get, and thus a
    corresponding of_code_put is needed in the error case.
    
    The problem was found using the following semantic match.
