    thermal/of: add missing of_node_put()
    
    [ Upstream commit 8a81cf96f5510aaf9a65d103f7405079a7b0fcc5 ]
    
    for_each_child_of_node performs an of_node_get on each
    iteration, so a break out of the loop requires an
    of_node_put.
    
    This was done using the Coccinelle semantic patch
    iterators/for_each_child.cocci
