If anyone has any objections, please let me know. ------------------ From: "Shuah Khan (Samsung OSG)" [ Upstream commit c7db6ffb831fd36a03485a0d88b1e505378975ad ] When sysctl test is skipped because of unmet dependencies and/or unsupported configuration, it exits with error which is treated as a fail by the Kselftest framework. This leads to false negative result even when the test could not be run. Change it to return kselftest skip code when a test gets skipped to clearly report that the test could not be run. Changed return code to kselftest skip code in skip error legs that check requirements and module probe test error leg. Kselftest framework SKIP code is 4 and the framework prints appropriate messages to indicate that the test is skipped.
