[ Upstream commit b4734507ac55cc7ea1380e20e83f60fcd7031955 ] After DisplayPort tunnel setup, we add verification that the DPRX capabilities read process completed. Otherwise, we bail out, teardown the tunnel, and try setup another DisplayPort tunnel using next available DP IN adapter. We do so till all DP IN adapters tried. This way, we avoid allocating DP IN adapter and (bandwidth for it) for unusable tunnel.

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.
