The default value is 0 meaning "no limit". However if 0
is specified on the command line it is instead silently
converted to 1. Further, the value is already validated
at point of use, there's no point in duplicating code
validating the value when it is set.
Simplify the code while making the behaviour more consistent
by using plain module_param.

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.
