mainlining shenanigans

Suspend routine disables wdog clk. Nevertheless, the watchdog subsystem is not aware of that and can still try to ping wdog through watchdog_ping_work. In order to prevent such condition and therefore prevent from system hang (caused by the wdog register access issued while the wdog clock is disabled) notify watchdog core that the ping worker should be canceled during watchdog core suspend and restored during resume.

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.
