This series is to fix device registration and unregistration.
The first patch addresses the resource is not released properly for a failure case during a device registration.
The second patch is to use mutex to protect unregistration flow.
The last three patches are for refactoring. Patch 03 explicitly uses the parent device handler. Patch 04 separates the success and failure flows for code readable and easier maintenance. Patch 05 improves the error handling by invoking specific functions for resource cleanup.
