Alan Stern 1e19a520a9 USB: gadget: Improve kerneldoc for usb_ep_dequeue()
Commit bf594c1070 ("USB: gadget: Document that certain ep operations
can be called in interrupt context") documented that usb_ep_dequeue()
may be called in a non-process context.  It follows that the routine
must not sleep or wait for events.

However, the routine's existing kerneldoc seems to imply that it will
wait until the request being cancelled has fully completed.  This is
not so, and thus the comment needs to be improved.  Misunderstanding
this point may very well have been responsible for a bug recently
uncovered in the f_fs function.

The updated comment explicitly says that the routine may return before
the request's completion handler is called.

README

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.
