Sorry if it's a matter of not having the latest version. Steve, please take a look at this. dfoley, even if your patch is correct your email client has severely corrupted the patch (changing tab characters into spaces, etc.) so if this patch is still needed you'll need to resubmit with your email client fixed to not corrupt the patch with formatting changes. > diff -purN a/drivers/net/smsc911x.c b/drivers/net/smsc911x.c > --- a/drivers/net/smsc911x.c 2008-12-18 10:03:27.000000000 -0800 > +++ b/drivers/net/smsc911x.c 2008-12-18 12:03:52.000000000 -0800 > @@ -822,7 +822,6 @@ static int __devinit smsc911x_mii_init(s > pdata->mii_bus->irq[i] = PHY_POLL; > > pdata->mii_bus->parent = &pdev->dev; > - dev_set_drvdata(&pdev->dev, &pdata->mii_bus); > > pdata->using_extphy = 0; > > @@ -1872,7 +1871,7 @@ static int __devexit smsc911x_drv_remove > res = platform_get_resource_byname(pdev, IORESOURCE_MEM, > "smsc911x-memory"); > if (!res) > - platform_get_resource(pdev, IORESOURCE_MEM, 0); > + res = platform_get_resource(pdev, IORESOURCE_MEM, 0); > > release_mem_region(res->start, res->end - res->start); > > -- > To unsubscribe from this list: send the line "unsubscribe netdev" in > the body of a message to majordomo@...r.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
