Do you actually know whether removing that lock fixes the reported bug? I agree, the lock should be removed for now. But I'd sure like to get some feedback about what's going wrong. It's starting to look as though we'd be a lot better off blocking device registration during sleep instead of failing it. Shouldn't resume_device() and suspend_device() now acquire the device semaphore before calling the various methods? That's the way they used to work.
