commit 489a71964f9d74e697a12cd0ace20ed829eb1f93 upstream.
We don't want vendors to be enabling this part of the clk code and
shipping it to customers. Exposing the ability to change clk frequencies
and parents via debugfs is potentially damaging to the system if folks
don't know what they're doing. Emit a strong warning so that the message
is clear: don't enable this outside of development systems.

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.
