Before assigning window data, we should check if the yuv2yuv vop-data
is set at all, because it looks like it can otherwise reference something
wrong, as I saw on my rk3188 today which ended up in a null pointer
dereference in vop_plane_atomic_update when accessing the yuv2yuv data.

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.
