video: omapdss: delete unneeded of_node_put
Device node iterators perform an of_node_put on each iteration, so putting
an of_node_put before a continue results in a double put.
A simplified version of the semantic match that finds this problem is as
follows (http://coccinelle.lip6.fr):
// <smpl>
@@
expression root,e;
local idexpression child;
iterator i;
@@
i(..., child, ...) {
... when != of_node_get(child)
* of_node_put(child);
...
* continue;
}
// </smpl>
