A workaround makes fbdev hot-unplugging work for framebuffers without device. The only user for this feature was offb. As each OF framebuffer now has an associated platform device, the workaround hould no longer be triggered. Update it with a warning and rewrite the comment. Fbdev drivers that trigger the hot-unplug workaround really need to be fixed.

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.
