The registration failure is because the crypto layer expects halg->statesize to be non-zero, and drivers/crypto/n2_core.c does not set it, causing breakage since possibly v4.2-rc1-182-g8996eafdcbad (commit by rmk): (1471) halg = &ahash->halg; halg->digestsize = tmpl->digest_size; Nevertheless, I think that the error pathing in n2_core.c should be made robust as well. Should I resubmit with a new commit message?
