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/mtd/nand/txx9ndfmc.c | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-) diff --git a/drivers/mtd/nand/txx9ndfmc.c b/drivers/mtd/nand/txx9ndfmc.c index ace46fd..c7c4f1d 100644 --- a/drivers/mtd/nand/txx9ndfmc.c +++ b/drivers/mtd/nand/txx9ndfmc.c @@ -298,11 +298,7 @@ static int __init txx9ndfmc_probe(struct platform_device *dev) drvdata = devm_kzalloc(&dev->dev, sizeof(*drvdata), GFP_KERNEL); if (!drvdata) return -ENOMEM; - if (!devm_request_mem_region(&dev->dev, res->start, - resource_size(res), dev_name(&dev->dev))) - return -EBUSY; - drvdata->base = devm_ioremap(&dev->dev, res->start, - resource_size(res)); + drvdata->base = devm_request_and_ioremap(&dev->dev, res); if (!drvdata->base) return -EBUSY; -- 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
