Huacai Chen 3031fb6109 drm/qxl: Use correct notify port address when creating cursor ring
commit 80e5f89da3ab949fbbf1cae01dfaea29f5483a75 upstream.

The command ring and cursor ring use different notify port addresses
definition: QXL_IO_NOTIFY_CMD and QXL_IO_NOTIFY_CURSOR. However, in
qxl_device_init() we use QXL_IO_NOTIFY_CMD to create both command ring
and cursor ring. This doesn't cause any problems now, because QEMU's
behaviors on QXL_IO_NOTIFY_CMD and QXL_IO_NOTIFY_CURSOR are the same.
However, QEMU's behavior may be change in future, so let's fix it.

P.S.: In the X.org QXL driver, the notify port address of cursor ring
      is correct.

README

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.
