The transferred length is incorrectly zeroed for cancelled isoc transfer TDs when the transfer ring stops on a cancelled TD with a 'Stop - Length Invalid' completion code. Length was always set to zero in these cases even if it should be set to the sum of the TRB transfer block lengths up to the TRB the ring stopped on, _excluding_ the one stopped on. No issues reported due to this isoc case. Found while inspecting related case in bulk transfer 'Stop - Length Invalid' handling. Change this so that 'Stop - Length Invalid' transfer completion cases always sum up TRB lengths instead of report a zero length.

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 reStructuredText 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.
