Date: Mon, 25 Jan 2016 17:51:21 +0100 From: Arnd Bergmann <arnd@...db.de> To: Herbert Xu <herbert@...dor.apana.org.au> Cc: linux-arm-kernel@...ts.infradead.org, Arnd Bergmann <arnd@...db.de>, linux-crypto@...r.kernel.org, "David S. Miller" <davem@...emloft.net>, linux-kernel@...r.kernel.org Subject: [PATCH] crypto: hash - select CRYPTO_HASH where needed The ghash and poly1305 hash implementations can be enabled when CONFIG_CRYPTO_HASH is turned off, causing a link error: crypto/built-in.o: In function `ghash_mod_init': (.init.text+0xd0): undefined reference to `crypto_register_shash' crypto/built-in.o: In function `ghash_mod_exit': (.exit.text+0xb4): undefined reference to `crypto_unregister_shash' crypto/built-in.o: In function `poly1305_mod_init': (.init.text+0xb4): undefined reference to `crypto_register_shash' crypto/built-in.o: In function `poly1305_mod_exit': (.exit.text+0x98): undefined reference to `crypto_unregister_shash' This adds an explicit 'select', like all other hashes have it.
