Commit f7d5bcd35d ("selftests: kselftest: Mark functions that
unconditionally call exit() as __noreturn") marked functions that call
exit() as __noreturn but it did not change the return type of these
functions from 'void' to 'int' like it should have (since a noreturn
function by definition cannot return an integer because it does not
return...) because there were many tests that return the result of the
ksft_exit functions, even though it has never been used due to calling
exit().
Now that all uses of 'return ksft_exit...()' have been cleaned up
properly, change the types of the ksft_exit...() functions to void to
match their __noreturn nature.

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.
