meson-gx-socinfo: add missing of_node_put after of_device_is_available
Add an of_node_put when a tested device node is not available. The semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ identifier f; local idexpression e; expression x; @@ e = f(...); ... when != of_node_put(e) when != x = e when != e = x when any if (<+...of_device_is_available(e)...+>) { ... when != of_node_put(e) ( return e; | + of_node_put(e); return ...; ) } // </smpl> Fixes: a9daaba2965e8 ("soc: Add Amlogic SoC Information driver") Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Kevin Hilman <khilman@baylibre.com>
