Double clear of reset requested state can lead to NULL pointer as it
will try to delete the timer twice. This can happen for example on a
race between abort from FW and pci error or reset. Avoid such case using
test_and_clear_bit() to verify only one time reset requested state clear
flow. Similarly use test_and_set_bit() to verify only one time reset
requested state set flow.

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.
