Jarkko Sakkinen 7ca110f267 tpm: Address !chip->auth in tpm_buf_append_hmac_session*() ... Unless tpm_chip_bootstrap() was called by the driver, !chip->auth can cause a null derefence in tpm_buf_hmac_session*(). Thus, address !chip->auth in tpm_buf_hmac_session*() and remove the fallback implementation for !TCG_TPM2_HMAC.
