MIPS: pci-rt3883: drop unneeded of_node_get
for_each_child_of_node performs an of_node_get on each iteration, so no
of_node_get is needed on breaking out of the loop when the device_node
structure is saved in another variable.
A simplified semantic match that finds this problem is as follows
(http://coccinelle.lip6.fr):
// <smpl>
@@
expression root;
local idexpression child;
@@
for_each_child_of_node(root, child) {
...
* of_node_get(child)
...
break;
}
// </smpl>
