From: Julia Lawall <redacted> Of_node_put supports NULL as its argument, so the initial test is not necessary. Suggested by Uwe Kleine-König. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression e; @@ -if (e) of_node_put(e); // </smpl> Signed-off-by: Julia Lawall <redacted> --- drivers/net/ethernet/xilinx/ll_temac_main.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-)
