Since commit "watchdog: Use depends instead of select for pretimeout
governors", it was possible to enable pretimeout governors but keep all
of them disabled. Doing this results in the following build failure.
../drivers/watchdog/watchdog_pretimeout.c:
In function ‘watchdog_register_governor’:
../drivers/watchdog/watchdog_pretimeout.c:139:26: error:
‘WATCHDOG_PRETIMEOUT_DEFAULT_GOV’ undeclared
if (!strncmp(gov->name, WATCHDOG_PRETIMEOUT_DEFAULT_GOV,
Since it does not make sense to enable pretimeout support but disable
all pretimeout governors, enforce that at least one of them is always
enabled.

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.
