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/keyboard/nspire-keypad.c | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) (limited to 'drivers/input/keyboard/nspire-keypad.c') diff --git a/drivers/input/keyboard/nspire-keypad.c b/drivers/input/keyboard/nspire-keypad.c index 20d872d6f603..b3e3edab6d9f 100644 --- a/drivers/input/keyboard/nspire-keypad.c +++ b/drivers/input/keyboard/nspire-keypad.c @@ -171,12 +171,6 @@ static int nspire_keypad_probe(struct platform_device *pdev) return -EINVAL; } - res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!res) { - dev_err(&pdev->dev, "missing platform resources\n"); - return -EINVAL; - } - keypad = devm_kzalloc(&pdev->dev, sizeof(struct nspire_keypad), GFP_KERNEL); if (!keypad) { @@ -208,6 +202,7 @@ static int nspire_keypad_probe(struct platform_device *pdev) return PTR_ERR(keypad->clk); } + res = platform_get_resource(pdev, IORESOURCE_MEM, 0); keypad->reg_base = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(keypad->reg_base)) return PTR_ERR(keypad->reg_base); -- cgit v1.2.3
