| |
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.
