This patch adds support for reading the trac register if atusb firmware reports tx done. There is currently a feature to compare a sequence number, if the payload is 1 it tells the driver only the sequence number is available if it's two there is additional the trac status register as payload. Currently the atusb_in_good() function determines if it's a tx done or rx done if according the payload length. This patch is doing the same and assumes this behaviour.

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.
