Date: Fri, 8 Aug 2014 12:07:43 +0200 From: Julia Lawall <Julia.Lawall@...6.fr> To: Anirudha Sarangi <anirudh@...inx.com> Cc: kernel-janitors@...r.kernel.org, John Linn <John.Linn@...inx.com>, Michal Simek <michal.simek@...inx.com>, netdev@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, Uwe Kleine-König <u.kleine-koenig@...gutronix.de> Subject: [PATCH 2/14] net: axienet: delete unneeded test before of_node_put From: Julia Lawall <Julia.Lawall@...6.fr> 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 <Julia.Lawall@...6.fr> --- drivers/net/ethernet/xilinx/xilinx_axienet_main.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/net/ethernet/xilinx/xilinx_axienet_main.c b/drivers/net/ethernet/xilinx/xilinx_axienet_main.c index 7b0a735..30e8608 100644 --- a/drivers/net/ethernet/xilinx/xilinx_axienet_main.c +++ b/drivers/net/ethernet/xilinx/xilinx_axienet_main.c @@ -1630,8 +1630,7 @@ static int axienet_of_remove(struct platform_device *op) axienet_mdio_teardown(lp); unregister_netdev(ndev); - if (lp->phy_node) - of_node_put(lp->phy_node); + of_node_put(lp->phy_node); lp->phy_node = NULL; iounmap(lp->regs); -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
