To make it compile on GitLab please add description of test to
a comments section, something like:

 * SUBTEST: async-flip-suspend-resume
 * Description: Verify the async flip functionality with suspend and resume cycle

add here:

 *
 * SUBTEST: overlay-atomic
 * Description: Verify overlay planes with async flips in atomic API
 */

Regards,
Kamil
