We get a newly introduced harmless warning when CONFIG_CRYPTO is disabled:
warning: (TCG_TPM && TRUSTED_KEYS && IMA) selects CRYPTO_HASH_INFO which has unmet direct dependencies (CRYPTO)
This adds another select to avoid the warning, consistent with other users
of the crypto code.
Fixes: c1f92b4b04ad ("tpm: enhance TPM 2.0 PCR extend to support multiple banks")

Ah, I see my mistake: I had made an identical patch earlier, which you merged
into linux-next, and I dropped it from my series after rebasing on
-next, but then
rebased again on mainline and did the new patch without checking whether
it was already fixed in -next.
I guess the warning is rare enough that we don't really need this in v4.11
even though it does apply there.

Ah. Right, now that I remember that was my conclusion. I'm sorry that
I did not remember to respond :-) If you think this would make sense
for 4.11 I could send it to stable.
