In commit 92833e8b5db6c209e9311ac8c6a44d3bf1856659 titled "net: sched: rename qdisc_destroy() to qdisc_put()" part of the functionality of qdisc_destroy() was moved into a (for linux-4.19.y) new function qdisk_put(), and the previous calls to qdisc_destroy() were changed to qdisk_put(). This made it similar to f.e. 5.10.y and current master. There was one part of qdisc_destroy() not moved over to qdisc_put() and that was the check for a NULL pointer, causing oopses. (See upstream commit: 6efb971ba8edfbd80b666f29de12882852f095ae) This patch fixes that.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
