Subject: [PATCH] tpm: select CONFIG_CRYPTO
Date: Tue, 14 Mar 2017 22:40:24 +0100	[thread overview]
Message-ID: <20170314214043.3895041-1-arnd@arndb.de> (raw)

As we need the CRYPTO_HASH_INFO implementation, we should also
select CRYPTO itself to avoid this build warning:

warning: (TCG_TPM && TRUSTED_KEYS && IMA) selects CRYPTO_HASH_INFO which has unmet direct dependencies (CRYPTO)

Fixes: c1f92b4b04ad ("tpm: enhance TPM 2.0 PCR extend to support multiple banks")
