Prevent downgrading the link training maximum lane count/rate if the sink is disconnected - and so the link training failure is expected. In such cases modeset failures due to the reduced max link params would be just confusing for user space (instead of which the correct thing it should act on is the sink disconnect signaled by a hotplug event, requiring a disabling modeset). v2: - Check the actual HPD state to handle the forced connector state case.

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.
