Sebastian Andrzej Siewior 1a9dcf69c7 selftests/futex: getopt() requires int as return value.
Mark reported that futex_priv_hash fails on ARM64.
It turns out that the command line parsing does not terminate properly
and ends in the default case assuming an invalid option was passed.

Use an int as the return type for getopt().

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.
