[ Upstream commit 9f45581f5e ]
There is a rare race condition that may happen during a Disconnect
Interrupt if we have a started request that happens to be
dequeued *after* completion of End Transfer command. If that happens,
that request will be left waiting for completion of an End Transfer
command that will never happen.
If End Transfer command has already completed before, we are safe to
giveback the request straight away.

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.
