powerpc/powermac: Add missing of_node_put
np is initialized to the result of calling a function that calls
of_node_get, so of_node_put should be called before the pointer is dropped.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression e,e1,e2;
@@
* e = \(of_find_node_by_type\|of_find_node_by_name\)(...)
... when != of_node_put(e)
when != true e == NULL
when != e2 = e
e = e1
// </smpl>
