Subject: [PATCH] ptp: Set lookup cookie when creating a PTP PPS source.
Date: Mon, 28 Jun 2021 11:25:33 -0700 [thread overview]
Message-ID: <20210628182533.2930715-1-jonathan.lemon@gmail.com> (raw)
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.
