crypto: chacha_generic - remove unnecessary setkey() functions
Use chacha20_setkey() and chacha12_setkey() from <crypto/internal/chacha.h> instead of defining them again in chacha_generic.c. Signed-off-by: Eric Biggers <ebiggers@google.com> Acked-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
