Subject: [PATCH] tpm: select CONFIG_CRYPTO
Date: Tue, 28 Feb 2017 22:12:55 +0100	[thread overview]
Message-ID: <20170228211326.3667625-1-arnd@arndb.de> (raw)

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")
