From 4382f37b78e02bb9a9d68cf0aef7928f0aaeff73 Mon Sep 17 00:00:00 2001 From: Steve Longerbeam <slongerbeam@gmail.com> Date: Sat, 29 Sep 2018 15:54:04 -0400 Subject: [PATCH] media: v4l2-fwnode: ignore endpoints that have no remote port parent Documentation/devicetree/bindings/media/video-interfaces.txt states that the 'remote-endpoint' property is optional. So v4l2_async_notifier_fwnode_parse_endpoint() should not return error if the endpoint has no remote port parent. Just ignore the endpoint, skip adding an asd to the notifier and return 0. __v4l2_async_notifier_parse_fwnode_endpoints() will then continue parsing the remaining port endpoints of the device.
