Michael Chan 927a7629be bnxt_en: Fix possible crash in bnxt_fw_reset_task().
[ Upstream commit b148bb238c02f0c7797efed026e9bba5892d2172 ]

bnxt_fw_reset_task() is run from a delayed workqueue.  The current
code is not cancelling the workqueue in the driver's .remove()
method and it can potentially crash if the device is removed with
the workqueue still pending.

The fix is to clear the BNXT_STATE_IN_FW_RESET flag and then cancel
the delayed workqueue in bnxt_remove_one().  bnxt_queue_fw_reset_work()
also needs to check that this flag is set before scheduling.  This
will guarantee that no rescheduling will be done after it is cancelled.

README

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.
