The radeon driver holds the console lock while suspending in-kernel DRM clients. This creates a circular dependency with the client-list mutex, which is supposed to be acquired first. Reported when combining radeon with another DRM driver. Therefore, do not take the console lock in radeon, but let the fbdev DRM client acquire the lock when needed. This is what all other DRM drivers so.

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 reStructuredText 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.
