In taprio_dump_class_stats() we don't need a reference to the root Qdisc once we get the reference to the child corresponding to this traffic class, so it's okay to overwrite "sch". But in a future patch we will need the root Qdisc too, so create a dedicated "child" pointer variable to hold the child reference. This also makes the code adhere to a more conventional coding style.

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.
