[Test] Users confirmed these patches work for them. [Fix] Commit a192aa923b66a (ACPI / LPSS: Consolidate runtime PM and system sleep handling) applies quirks for both runtime and system suspend. This causes problems for some systems, so avoid using quirks on S3 and S4. [Regression Potential] Low. These patches are in upstream stable, and it brings back driver's old behavior. Rafael J.
