I would think how to fix it.

Thanks for your response. I have some questions. What are the flows when
the system resume follows a system suspend which follows a autosuspend?
Are they as following?
1. suspend() with PMSG_IS_AUTO for autosuspned.
2. suspend() for system suspend.
3. resume() for system resume.
And, should the device exist autosuspend before (2)?
Best Regards,
Hayes
