From bad6a185b4d6f81d0ed2b6e4c16307969f160b95 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 18 May 2016 16:55:56 +0200 Subject: [PATCH] crypto: public_key: select CRYPTO_AKCIPHER In some rare randconfig builds, we can end up with ASYMMETRIC_PUBLIC_KEY_SUBTYPE enabled but CRYPTO_AKCIPHER disabled, which fails to link because of the reference to crypto_alloc_akcipher: crypto/built-in.o: In function `public_key_verify_signature': :(.text+0x110e4): undefined reference to `crypto_alloc_akcipher' This adds a Kconfig 'select' statement to ensure the dependency is always there.
