(Upstream commit 96330407f8).
When parsing the remote endpoint of an output port, we do :
rport = of_graph_get_remote_port(ep);
rparent = of_graph_get_remote_port_parent(ep);
and then parse the "remote_port" as if it was the remote endpoint,
which is wrong. The code worked fine because we used endpoint number
as the port number. Let us fix it and optimise a bit as:
remote_ep = of_graph_get_remote_endpoint(ep);
if (remote_ep)
remote_parent = of_graph_get_port_parent(remote_ep);
and then, parse the remote_ep for the port/endpoint details.

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.
