clk: imx27: add missing of_node_put
for_each_compatible_node performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put. The semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ local idexpression n; expression e; @@ for_each_compatible_node(n,...) { ... ( of_node_put(n); | e = n | + of_node_put(n); ? break; ) ... } ... when != n // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
