From: Julia Lawall <julia@xxxxxxx> Reimplement a call to devm_request_mem_region followed by a call to ioremap or ioremap_nocache by a call to devm_request_and_ioremap. The semantic patch that makes this transformation is as follows: (http://coccinelle.lip6.fr/) // <smpl> @nm@ expression myname; identifier i; @@ struct platform_driver i = { .driver = { .name = myname } }; @@ expression dev,res,size; expression nm.myname; @@ -if (!devm_request_mem_region(dev, res->start, size, - \(res->name\|dev_name(dev)\|myname\))) { - ... - return ...; -} ... when != res->start ( -devm_ioremap(dev,res->start,size) +devm_request_and_ioremap(dev,res) | -devm_ioremap_nocache(dev,res->start,size) +devm_request_and_ioremap(dev,res) ) ... when any when != res->start // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/gpio/gpio-tegra.c | 9 +-------- 1 file changed, 1 insertion(+), 8 deletions(-) diff --git a/drivers/gpio/gpio-tegra.c b/drivers/gpio/gpio-tegra.c index 61044c8..bdc2937 100644 --- a/drivers/gpio/gpio-tegra.c +++ b/drivers/gpio/gpio-tegra.c @@ -361,14 +361,7 @@ static int __devinit tegra_gpio_probe(struct platform_device *pdev) return -ENODEV; } - if (!devm_request_mem_region(&pdev->dev, res->start, - resource_size(res), - dev_name(&pdev->dev))) { - dev_err(&pdev->dev, "Couldn't request MEM resource\n"); - return -ENODEV; - } - - regs = devm_ioremap(&pdev->dev, res->start, resource_size(res)); + regs = devm_request_and_ioremap(&pdev->dev, res); if (!regs) { dev_err(&pdev->dev, "Couldn't ioremap regs\n"); return -ENODEV; -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
