Describe the bug
Recently, our CI detected the suspend/resume issue on 2 Chrome devices, One plaform is TGLU_VOLT_SDW and another one is CML_HEL_RT5682. There's no much logs available during the test, system failed to resume from suspending in the first round of testing.
From the history of our CI testing, we determined this is a kernel regression.
Bisect result shows that this issue is caused by an acpi change from upstream rebase.
