How does kernel manage name conflict if multiple misc device requesting  
"enclave" ?

And the attributes for a udev rule to match this device according to  
udevadm output are:
SUBSYSTEM=="misc",KERNEL=="enclave"

Is that specific enough to uniquely match this device?

Similar questions for the "provision" device introduced later in this  
series.

Thanks
