René Rebe bf66b535da fix it87_wdt early reboot by reporting running timer
[ Upstream commit 88b2ab3464 ]

Some products, such as the Ugreen DXP4800 Plus NAS, ship with the it87
wdt enabled by the firmware and a broken BIOS option that does not
allow to change the time or turn it off. As this makes installing
Linux rather difficult, change the it87_wdt to report it running to
the watchdog core.

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.
