The uvc_video_enable function of the uvc-gadget driver is dequeing and immediately deallocs all requests on its disable codepath. This is not save since the dequeue function is async and does not ensure that the requests are left unlinked in the controller driver. By adding the ep_free_request into the completion path of the requests we ensure that the request will be properly deallocated.

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.
