The bootloader might already enable the watchdog to catch hangs during the boot process. In that case the kernel needs to ping the watchdog temporarily until userspace is fully started. Add a check for this in the probe() function and set the WDOG_HW_RUNNING flag to make the watchdog core handle this automatically.

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.
