During the debugging process related to a hot-plug problem with 4k display, we realized that we had some issues related to the global state validation. This problem was not explicitly highlighted in the dmesg log, for this reason, this commit adds a function that converts `enum dc_status` to a human-readable string and appends the proper warning message in case of failure.

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.
