A recent patch has moved the workqueue cleanup logic before
calling unregister_netdev() in bnxt_remove_one(). This caused a
regression because the workqueue can be restarted if the device is
still open. Workqueue cleanup must be done after unregister_netdev().
The workqueue will not restart itself after the device is closed.
Call bnxt_cancel_sp_work() after unregister_netdev() and
call bnxt_dl_fw_reporters_destroy() after that. This fixes the
regession and the original NULL ptr dereference issue.

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.
