[PATCH v2 00/13] selftests: Fix build warnings and errors

[Guenter Roeck <linux@roeck-us.net>]

This series fixes build warnings and errors observed when trying to build
selftests.

v2: Emphasize that the patch series fixes build warnings and errors
    which are seen even if -Werror is not provided.
    Fix usage of cc-option.
    For "ignoring return value" warnings, use perror() to display an error
    message if the affected function returns an error.
