commit 65150c9cc3 upstream.
iwl_mvm_ptp_remove() calls cancel_delayed_work_sync() only after
ptp_clock_unregister() and clearing ptp_data state (ptp_clock,
ptp_clock_info, last_gp2).
This creates a race where the delayed work iwl_mvm_ptp_work() can
execute between ptp_clock_unregister() and cancel_delayed_work_sync(),
observing partially cleared PTP state.
Move cancel_delayed_work_sync() before ptp_clock_unregister() to
ensure the delayed work is fully stopped before any PTP cleanup
begins.

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 reStructuredText 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.
