* phy: mt65xx-usb3: add missing of_node_putJulia Lawall2015-12-031-7/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | for_each_child_of_node performs an of_node_get on each iteration, so a return from the middle of the loop requires an of_node_put. A simplified version of the semantic patch that finds this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ expression root,e; local idexpression child; @@ for_each_child_of_node(root, child) { ... when != of_node_put(child) when != e = child ( return child; | * return ...; ) ... } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
