Dmitry Baryshkov abd1186415 drm/msm/mdp5: fix cursor-related warnings 
commit c491a0c7bbf3a64732cb8414021429d15ec08eec upstream.

Since f35a2a99100f ("drm/encoder: make encoder control functions
optional") drm_mode_config_validate would print warnings if both cursor
plane and cursor functions are provided. Restore separate set of
drm_crtc_funcs to be used if separate cursor plane is provided.

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.
