If the streamoff call was triggered by some previous disconnect or userspace application shutdown the uvc_function_setup_continue should not be called and the state should not be overwritten. For this situation the set_alt(0) was never called and the streaming ep has no USB_GADGET_DELAYED_STATUS pending. Since the state then was already updated before we also omit the state update.

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.
