kill_fq removes a complete frame queue, it needs to free the qman_fq
in the last. Else kmemleak will report the below warning:
unreferenced object 0xffff800073085c80 (size 128):

And check where the function kill_fq() is called to remove
the additional kfree to qman_fq and avoid re-calling the released qman_fq.

README
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.
