If a request is dequeued, the transfer is cancelled. Give back all the started requests. In most scenarios, the function driver dequeues all requests of a transfer when there's a failure. If the function driver follows this, then it's fine. If not, then we'd be skipping TRBs at different points within the dequeue and enqueue pointers, making dequeue/enqueue pointers useless. To enforce and make sure that we're properly skipping TRBs, cancel all the started requests and give back all the cancelled requests to the function drivers.

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.
