Hi, This series addresses some enumeration ordering issues by using information from _DEP to defer the enumeration of devices that are likely to depend on operation region (OpRegion) handlers supplied by the drivers of other devices. This allows the OpRegion suppliers to be probed and start working before the devices depending on them are enumerated. Please see the patch changelogs for details. Hans, please test this series on the system with OpRegion dependencies in control methods used for device enumeration. Thanks!
