From: Julia Lawall <julia.law...@lip6.fr> 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/) // <smpl> @@ 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); // </smpl> Signed-off-by: Julia Lawall <julia.law...@lip6.fr> --- drivers/tty/serial/ar933x_uart.c | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) diff --git a/drivers/tty/serial/ar933x_uart.c b/drivers/tty/serial/ar933x_uart.c index 3f5517f..a712a3f 100644 --- a/drivers/tty/serial/ar933x_uart.c +++ b/drivers/tty/serial/ar933x_uart.c @@ -640,12 +640,6 @@ static int ar933x_uart_probe(struct platform_device *pdev) if (id > CONFIG_SERIAL_AR933X_NR_UARTS) return -EINVAL; - mem_res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!mem_res) { - dev_err(&pdev->dev, "no MEM resource\n"); - return -EINVAL; - } - irq_res = platform_get_resource(pdev, IORESOURCE_IRQ, 0); if (!irq_res) { dev_err(&pdev->dev, "no IRQ resource\n"); @@ -659,6 +653,7 @@ static int ar933x_uart_probe(struct platform_device *pdev) port = &up->port; + mem_res = platform_get_resource(pdev, IORESOURCE_MEM, 0); port->membase = devm_ioremap_resource(&pdev->dev, mem_res); if (IS_ERR(port->membase)) return PTR_ERR(port->membase); -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
