Thomas Zimmermann 2d70b9a148 drm/mgag200: Acquire I/O-register lock in atomic_commit_tail function
Hold I/O-register lock in atomic_commit_tail to protect all pipeline
updates at once. Protects against concurrent I/O access in get-modes
helper.

Complex modesetting operations involve mode changes, plane updates and
possibly BMC updates. Make all this atomic wrt to reading display modes
via EDID. It's not so much an issue with simple-KMS helpers, but will
become necessary for using regular atomic helpers.

v4:
	* remove empty line

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.
