The debugfs code is provided an array of a single drm_connector. Then to access the connector, the list of all connectors of the DRM device is traversed and all non-DisplayPort connectors are skipped, to find the one and only DisplayPort connector. But as we move to support multiple DisplayPort controllers this will now find multiple connectors and has no way to distinguish them. Pass the single connector to dp_debug_get() and use this in the debugfs functions instead, both to simplify the code and the support the multiple instances.

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.
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.
