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 --- drivers/spi/spi-bcm63xx.c | 8 +------- drivers/spi/spi-bfin-v3.c | 8 +------- 2 files changed, 2 insertions(+), 14 deletions(-) diff --git a/drivers/spi/spi-bcm63xx.c b/drivers/spi/spi-bcm63xx.c index 4ac028d..2b5c692 100644 --- a/drivers/spi/spi-bcm63xx.c +++ b/drivers/spi/spi-bcm63xx.c @@ -342,13 +342,6 @@ 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"); @@ -375,6 +368,7 @@ 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 603d7e9..d5bab00 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); -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
