drm/mgag200: Move cursor-image update to mgag200_show_cursor()
Thomas Zimmermann authored

Separating the management of buffer objects from updating the hardware
cursor buffer gives the code more structure. While doing this, we can
further split the image-update code into code for writing the buffer,
setting the base scan-out address, and enabling the cursor. The first
two operations are in dedicated functions update() and set_base().

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.
