Qiushi Wu 1a17c51d91 usb: gadget: fix potential double-free in m66592_probe.
[ Upstream commit 44734a594196bf1d474212f38fe3a0d37a73278b ]

m66592_free_request() is called under label "err_add_udc"
and "clean_up", and m66592->ep0_req is not set to NULL after
first free, leading to a double-free. Fix this issue by
setting m66592->ep0_req to NULL after the first free.

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.
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.
