If the problem is solved, change the tag 'verification-needed- disco' to 'verification-done-disco'. If the problem still exists, change the tag 'verification-needed-disco' to 'verification-failed-disco'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

[Fix] Some TBT and other ACPI devices share the same power resource, when system goes to s2idle. PME polling thread continue bringing up devices to D0 mode. Use cached ACPI device power state will avoid this issue. [Test] Verified on 2 hardware. Tests result are good. [Regression Potential] Medium, upstream patches cherry-picked. Since these hareware is only supported by 5.0+ kernel, I set B-OEM- OSP1 and disco+ kernel tag.
