Hi Wolfram: This is the first and only one of the patch series I looked at. > diff --git a/drivers/memory/tegra20-mc.c b/drivers/memory/tegra20-mc.c [] > @@ -218,8 +218,6 @@ static int tegra20_mc_probe(struct platform_device *pdev) > struct resource *res; > > res = platform_get_resource(pdev, IORESOURCE_MEM, i); > - if (!res) > - return -ENODEV; > mc->regs[i] = devm_ioremap_resource(&pdev->dev, res); I'm not so sure this is appropriate. devm_ioremap_resource returns ERR_PTR(-EINVAL) for null resource so this changes the return. devm_ioremap_resource also emits a noisy dev_err message when resource is NULL. It's a probe and before the message log would be silent but now there's a new dmesg. Perhaps that should be mentioned in the changelog here and elsewhere in the series. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
