From eacd0c47966b918f10c7ac1a91dd9fccb0f58ddd Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 15 Aug 2013 00:07:43 -0700 Subject: Input: tegra-kbc - 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 Signed-off-by: Dmitry Torokhov --- drivers/input/keyboard/tegra-kbc.c | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) (limited to 'drivers/input') diff --git a/drivers/input/keyboard/tegra-kbc.c b/drivers/input/keyboard/tegra-kbc.c index b46142f78ef2..9cd20e6905a0 100644 --- a/drivers/input/keyboard/tegra-kbc.c +++ b/drivers/input/keyboard/tegra-kbc.c @@ -638,12 +638,6 @@ static int tegra_kbc_probe(struct platform_device *pdev) if (!tegra_kbc_check_pin_cfg(kbc, &num_rows)) return -EINVAL; - res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!res) { - dev_err(&pdev->dev, "failed to get I/O memory\n"); - return -ENXIO; - } - kbc->irq = platform_get_irq(pdev, 0); if (kbc->irq < 0) { dev_err(&pdev->dev, "failed to get keyboard IRQ\n"); @@ -658,6 +652,7 @@ static int tegra_kbc_probe(struct platform_device *pdev) setup_timer(&kbc->timer, tegra_kbc_keypress_timer, (unsigned long)kbc); + res = platform_get_resource(pdev, IORESOURCE_MEM, 0); kbc->mmio = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(kbc->mmio)) return PTR_ERR(kbc->mmio); -- cgit v1.2.3
