So, if any, we'd need put a mutex around the fallback loader code.
And, the mutex should be rather per device, not a global one.

Or we may trick it by appending the second parallel caller into the
same wait queue, but the code will be more complex, so I don't think
worth for it.
For now I'm thinking of a new API with a devname prefix to the driver.
I'll have to test if that works, but not sure if I'll get to it today
before my vacation starts (today).
Have a good vacation.
