Subject: [PATCH] ptp: Set lookup cookie when creating a PTP PPS source.
When creating a PTP device, the configuration block allows
creation of an associated PPS device. However, there isn't
any way to associate the two devices after creation.
Set the PPS cookie, so pps_lookup_dev(ptp) performs correctly.
