Message-Id: <1453740644-1980309-1-git-send-email-arnd@arndb.de> Date: Mon, 25 Jan 2016 17:50:34 +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 1/2] crypto: jitterentropy - always select CRYPTO_RNG When building the jitterentropy driver by itself, we get a link error when CRYPTO_RNG is not enabled as well: crypto/built-in.o: In function `jent_mod_init': jitterentropy-kcapi.c:(.init.text+0x98): undefined reference to `crypto_register_rng' crypto/built-in.o: In function `jent_mod_exit': jitterentropy-kcapi.c:(.exit.text+0x60): undefined reference to `crypto_unregister_rng' This moves the 'select CRYPTO_RNG' from CRYPTO_DRBG to CRYPTO_JITTERENTROPY to ensure the API is always there when it's used, not just when DRBG is also enabled.
