[ Upstream commit d4dff8043ea5b93a30cb9b19d4407bd506a6877a ] isochronous endpoints do not support streams, meaning that there is only one ring per endpoint. Avoid double-fetching the transfer event DMA to get the ring. Also makes passing the event to skip_isoc_td() uncecessary.

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.
