[PATCH] mac802154: select CRYPTO when needed

[Marcel Holtmann]

Hi Arnd,

> 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.
