Many function calls are done this way:
if ((retval = func()) != 0)
return retval;
while we expect in the kernel function calls like:
retval = func();
if (retval)
return retval;
Apply this change where possible and also use "ret" instead of
"retval" in ns_init_module for consistency, as it is only used in this
function.

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.
