2018-05-30selftests: media_tests: return Kselftest Skip code for skipped testsShuah Khan (Samsung OSG)1-4/+4
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. Signed-off-by: Shuah Khan (Samsung OSG) <shuah@kernel.org>

2016-02-25selftests: add a new test for Media Controller APIShuah Khan1-0/+94
This test opens user specified Media Device and calls MEDIA_IOC_DEVICE_INFO ioctl in a loop once every 10 seconds. This test is for detecting errors in device removal path. Usage: sudo ./media_device_test -d /dev/mediaX While test is running, remove the device and ensure there are no use after free errors and other Oops in the dmesg. Enable KaSan kernel config option for use-after-free error detection. Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
