[PATCH for-4.18 v2] automation: fix race condition in adl-suspend test
If system suspends too quickly, the message for the test controller to wake up the system may be not sent to the console before suspending. This will cause the test to timeout. Fix this by calling sync on the console and waiting a bit after printing the message. The test controller then resumes the system 30s after the message, so as long as the delay + suspending takes less time it is okay. Signed-off-by: Marek Marczykowski-Górecki --- This is consistent with the observation that sync_console "fixes" the issue.

For staging 4.18: Release-acked-by: Henry Wang I will remove the commit moratorium for staging once OSSTest does a successful sync between staging and master. Thanks. Kind regards, Henry
