Subject: [PATCH 19/24] selftests: media_tests: return Kselftest Skip code for skipped tests
Date:   Fri,  4 May 2018 19:13:23 -0600
Message-Id: <20180505011328.32078-19-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 media_tests 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.

Change it to use ksft_exit_skip() when the test is skipped.
