From 8602e40fc8132383298f304ae060d80f210be23c Mon Sep 17 00:00:00 2001 From: Jonathan Lemon Date: Mon, 28 Jun 2021 11:25:33 -0700 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. Signed-off-by: Jonathan Lemon Signed-off-by: David S.
