From ef0aca7f2f94a24d82aea0b74ae7a71c611e4895 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 15 Aug 2013 00:08:17 -0700 Subject: Input: keyboard, serio - simplify use of devm_ioremap_resource Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource. Move the call to platform_get_resource adjacent to the call to devm_ioremap_resource to make the connection between them more clear. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ expression pdev,res,n,e,e1; expression ret != 0; identifier l; @@ - res = platform_get_resource(pdev, IORESOURCE_MEM, n); ... when != res - if (res == NULL) { ... \(goto l;\|return ret;\) } ... when != res + res = platform_get_resource(pdev, IORESOURCE_MEM, n); e = devm_ioremap_resource(e1, res); // Signed-off-by: Julia Lawall Acked-by: Viresh Kumar Signed-off-by: Dmitry Torokhov --- drivers/input/serio/arc_ps2.c | 7 +------ drivers/input/serio/olpc_apsp.c | 3 --- 2 files changed, 1 insertion(+), 9 deletions(-) (limited to 'drivers/input/serio') diff --git a/drivers/input/serio/arc_ps2.c b/drivers/input/serio/arc_ps2.c index 3fb7727c8ea5..8024a6d7fccb 100644 --- a/drivers/input/serio/arc_ps2.c +++ b/drivers/input/serio/arc_ps2.c @@ -189,12 +189,6 @@ static int arc_ps2_probe(struct platform_device *pdev) int irq; int error, id, i; - res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!res) { - dev_err(&pdev->dev, "no IO memory defined\n"); - return -EINVAL; - } - irq = platform_get_irq_byname(pdev, "arc_ps2_irq"); if (irq < 0) { dev_err(&pdev->dev, "no IRQ defined\n"); @@ -208,6 +202,7 @@ static int arc_ps2_probe(struct platform_device *pdev) return -ENOMEM; } + res = platform_get_resource(pdev, IORESOURCE_MEM, 0); arc_ps2->addr = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(arc_ps2->addr)) return PTR_ERR(arc_ps2->addr); diff --git a/drivers/input/serio/olpc_apsp.c b/drivers/input/serio/olpc_apsp.c index 818aa466b5d2..51b1d40cc286 100644 --- a/drivers/input/serio/olpc_apsp.c +++ b/drivers/input/serio/olpc_apsp.c @@ -183,9 +183,6 @@ static int olpc_apsp_probe(struct platform_device *pdev) np = pdev->dev.of_node; res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!res) - return -ENOENT; - priv->base = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(priv->base)) { dev_err(&pdev->dev, "Failed to map WTM registers\n"); -- cgit v1.2.3
