When "tmr_atboot" module param is set, the watchdog is started in driver's probe. In that case, also set WDOG_HW_RUNNING bit to let watchdog core driver know it's running. This way watchdog core can kick the watchdog for us (if CONFIG_WATCHDOG_HANDLE_BOOT_ENABLED option is enabled), until user space takes control. WDOG_HW_RUNNING bit must be set before registering the watchdog. So the "tmr_atboot" handling code is moved before watchdog registration, to avoid performing the same check twice. This is also logical because WDOG_HW_RUNNING bit makes WDT core expect actually running watchdog.

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.
