Thanks a lot for catching this Konrad. The correct SID pairs are <0x80 0x0> and <0x81 0x0>.
(I hope I don't need to pad them?)

Unfortunately, I could only validate driver probe on my limited ramdisk environment:

[    4.583802] qcrypto 1dfa000.crypto: Crypto device found, version 5.9.1

I was waiting for Wenjia to run the full crypto user-space test suite once. I'll update the
SIDs and wait for a Tested-by from him.

Regards,
Harshal
