Three new tests added:
1. Send get random cmd, read header in 1st read, read the rest in second
read - expect success
2. Send get random cmd, read only part of the response, send another
get random command, read the response - expect success
3. Send get random cmd followed by another get random cmd, without
reading the first response - expect the second cmd to fail with -EBUSY

You are missing a cover letter from this patch set. Please have it in
v2. Also use tag "selftests/tpm2" instead of having two tags in the
short summaries. Now they look a bit weird.

Since when is the cover letter mandatory?
I understand that is helps for a complicated patch set
to explain the problem and solution in the cover letter,
but for this simple test case addition what's the point?
And there is nothing forcing a cover letter in
https://www.kernel.org/doc/html/v4.20/process/submitting-patches.html
Also double tags seams to be quite common for selftest.
See git log tools/testing/selftests/

OK, cool.

Prefer slash for TPM specific commits.
I can merge this after those extra logs are removed.
