memory: tegra: Delete unneeded of_node_put()
for_each_child_of_node() performs an of_node_put() on each iteration, so putting an of_node_put() before a continue results in a double put. The semantic match that finds this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ expression root,e; local idexpression child; iterator name for_each_child_of_node; @@ for_each_child_of_node(root, child) { ... when != of_node_get(child) * of_node_put(child); ... * continue; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Thierry Reding <treding@nvidia.com>
