When the watchdog was configured for nowayout, and after the userspace watchdog daemon closed the dev node without sending the magic character, unloading this module stopped the watchdog hardware, which was clearly a problem. Besides, unloading the module is not possible when the userspace watchdog daemon is running, so it's safe to assume that we don't need to stop the watchdog hardware in the jz4740_wdt_remove() function. For this reason, the jz4740_wdt_remove() function can then be dropped alltogether.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
