Subject: [PATCH 11/24] selftests: intel_pstate: return Kselftest Skip code for skipped tests
Date:   Fri,  4 May 2018 19:13:15 -0600
Message-Id: <20180505011328.32078-11-shuah@kernel.org>
In-Reply-To: <20180505011328.32078-1-shuah@kernel.org>
References: <20180505011328.32078-1-shuah@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

When intel_pstate test is skipped because of unmet dependencies and/or
unsupported configuration, it returns 0 which is treated as a pass
by the Kselftest framework. This leads to false positive 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.

Kselftest framework SKIP code is 4 and the framework prints appropriate
messages to indicate that the test is skipped.
