Isn't it saying that the ACPI is in error to include more resource types that aren't part of specifying the AMBA primecell device? Maybe it should be dev_err(), because it's technically an error...

You are assuming that it does return a positive non-zero value in the first place. -- RMK's Patch system: http://www.arm.linux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
