Dave:
In this section from usb_new_device():
if (!is_targeted(udev)) {
/* Maybe it can talk to us, though we can't talk to it.
* (Includes HNP test device.)
*/
if (udev->bus->b_hnp_enable || udev->bus->is_b_host) {
err = __usb_port_suspend(udev, udev->bus->otg_port);
if (err < 0)
dev_dbg(&udev->dev, "HNP fail, %d\n", err);
}
Is there any reason to call __usb_port_suspend() rather than
usb_port_suspend()? After all, an OTG device is required to have no
more than one USB connection, so the port number would always be equal
to udev->portnum and to 1.
