Christoph Hellwig 67f30ad19c au1100fb: fix DMA API abuse
Virtual addresses return from dma(m)_alloc_coherent are opaque in what
backs then, and drivers must not poke into them.  Switch the driver
to use the generic DMA API mmap helper to avoid these games.

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.
