From 73e85ed36a96324a2ba5990024f621bf9907fbd5 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 19 May 2015 14:18:35 +0200 Subject: [PATCH] mac802154: select CRYPTO when needed The mac802154 subsystem uses functions from the crypto layer and correctly selects the individual crypto algorithms, but fails to build when the crypto layer is disabled altogether: crypto/built-in.o: In function `crypto_ctr_free': :(.text+0x80): undefined reference to `crypto_drop_spawn' crypto/built-in.o: In function `crypto_rfc3686_free': :(.text+0xac): undefined reference to `crypto_drop_spawn' crypto/built-in.o: In function `crypto_ctr_crypt': :(.text+0x2f0): undefined reference to `blkcipher_walk_virt_block' :(.text+0x2f8): undefined reference to `crypto_inc' To solve that, this patch also selects the core crypto code, like all other users of that code do.
