Julia Lawall 182f30e4b9 powerpc/cell: Add of_node_put to avoid memory leak 
Add calls to of_node_put in the error handling code following calls to
of_find_node_by_path and of_find_node_by_phandle.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r exists@
local idexpression x;
expression E,E1;
statement S;
@@

*x =
(of_find_node_by_path
|of_find_node_by_name
|of_find_node_by_phandle
|of_get_parent
|of_get_next_parent
|of_get_next_child
|of_find_compatible_node
|of_match_node
)(...);
...
if (x == NULL) S
<... when != x = E
*if (...) {
  ... when != of_node_put(x)
      when != if (...) { ... of_node_put(x); ... }
(
  return <+...x...+>;

*  return ...;
)
}

of_node_put(x);
