Thierry Reding e9827d8ea2 drm/fb-helper: Add top-level lock
Introduce a new top-level lock for the FB helper code. This will allow
better locking granularity and avoid the need to abuse modeset locking
for this purpose instead.

This patch just adds the new lock everywhere we currently grab
mode_config->mutex (explicitly, or through drm_modeset_lock_all).
Follow-up patches will push the kms locking down into only the places
that need it.

v2:
- use lockdep_assert_held
- use drm_fb_helper_for_each_connector where possible
- use the new top-level lock consistently, i.e. in all the places
  we're currently acquiring mode_config.mutex.
- small polish to the kerneldoc

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
