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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
