commitfe49df60cdupstream. Avoid xHC host from processing a cancelled URB by always turning cancelled URB TDs into no-op TRBs before queuing a 'Set TR Deq' command. If the command fails then xHC will start processing the cancelled TD instead of skipping it once endpoint is restarted, causing issues like Babble error. This is not a complete solution as a failed 'Set TR Deq' command does not guarantee xHC TRB caches are cleared.

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.
