commit 2ff124d597c2df8696169ce0006fc974c49a4569 upstream.
The ev_file is an optional parameter for CQ creation. If the parameter
is not passed, the ev_file pointer will be NULL. Using that pointer
to set the cq_context will result in an OOPs.
Verify that ev_file is not NULL before using.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
