Thus, there may exist a data race for "hotplug->enabled".
Either it does exist, or it doesn't.
If it exists, it needs to be fixed. If it doesn't exist, nothing
needs to be done.
Which is the case?
I only read the code and find this possible data race.
It is not found in real driver execution.
I am not sure of it, so I use "may" and "possible" here.
