After this patch I get the following build error: ERROR: "acpi_get_physical_device_location" [drivers/usb/core/usbcore.ko] undefined! Lan, please retest these, and resend them, with Matthew's other ACPI patch, after it's all working properly, and you have fixed this all up. I've dropped all of these from my mailboxes now, you need to start over. Also, when you forward on a patch like this, and the others, please also sign-off-by: on it, or at least Ack: it, to keep you in the chain of bug reporting and stuff. greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
