MIPS: pci-rt3883: drop unneeded of_node_get
Author: Julia Lawall <Julia.Lawall@lip6.fr> 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): // @@ expression root; local idexpression child; @@ for_each_child_of_node(root, child) { … …
