Subject: [PATCH 1/6] usbcore: store each usb_device's level in the tree
Message-ID: <[EMAIL PROTECTED]>
This patch (as778) adds a field to struct usb_device to store the
device's level in the USB tree. In itself this number isn't really
important. But the overhead is very low, and in a later patch it will
be used for preventing bogus warnings from the lockdep checker.
