From de0fa83c410d8ad4bcee72814562eb1be7551edf Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 14 Aug 2013 11:11:09 +0200 Subject: spi/spi-{bcm63xx.c,bfin-v3.c}: 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: Mark Brown --- drivers/spi/spi-bcm63xx.c | 8 +------- drivers/spi/spi-bfin-v3.c | 8 +------- 2 files changed, 2 insertions(+), 14 deletions(-) (limited to 'drivers/spi') diff --git a/drivers/spi/spi-bcm63xx.c b/drivers/spi/spi-bcm63xx.c index 9fd7a39b802..a21fef4a3bb 100644 --- a/drivers/spi/spi-bcm63xx.c +++ b/drivers/spi/spi-bcm63xx.c @@ -360,13 +360,6 @@ static int bcm63xx_spi_probe(struct platform_device *pdev) struct bcm63xx_spi *bs; int ret; - r = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!r) { - dev_err(dev, "no iomem\n"); - ret = -ENXIO; - goto out; - } - irq = platform_get_irq(pdev, 0); if (irq < 0) { dev_err(dev, "no irq\n"); @@ -393,6 +386,7 @@ static int bcm63xx_spi_probe(struct platform_device *pdev) platform_set_drvdata(pdev, master); bs->pdev = pdev; + r = platform_get_resource(pdev, IORESOURCE_MEM, 0); bs->regs = devm_ioremap_resource(&pdev->dev, r); if (IS_ERR(bs->regs)) { ret = PTR_ERR(bs->regs); diff --git a/drivers/spi/spi-bfin-v3.c b/drivers/spi/spi-bfin-v3.c index 603d7e91085..d5bab00f190 100644 --- a/drivers/spi/spi-bfin-v3.c +++ b/drivers/spi/spi-bfin-v3.c @@ -792,13 +792,6 @@ static int bfin_spi_probe(struct platform_device *pdev) return -ENXIO; } - /* get register base and tx/rx dma */ - mem = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!mem) { - dev_err(dev, "can not get register base\n"); - return -ENXIO; - } - res = platform_get_resource(pdev, IORESOURCE_DMA, 0); if (!res) { dev_err(dev, "can not get tx dma resource\n"); @@ -838,6 +831,7 @@ static int bfin_spi_probe(struct platform_device *pdev) drv_data->pin_req = info->pin_req; drv_data->sclk = sclk; + mem = platform_get_resource(pdev, IORESOURCE_MEM, 0); drv_data->regs = devm_ioremap_resource(dev, mem); if (IS_ERR(drv_data->regs)) { ret = PTR_ERR(drv_data->regs); -- cgit v1.2.3-70-g09d2
