Thomas Zimmermann fff8e05044 drm/radeon: Do not hold console lock during resume
The function radeon_resume_kms() acquires the console lock. It is
inconsistent, as it depends on the notify_client argument. That
lock then covers a number of suspend operations that are unrelated
to the console.

Remove the calls to console_lock() and console_unlock() from the
radeon function. The console lock is only required by DRM's fbdev
emulation, which acquires it as necessary.

Also fixes a possible circular dependency between the console lock
and the client-list mutex, where the mutex is supposed to be taken
first.

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.
