crt_u.compress (struct compress_tfm) is pointless because its two fields, ->cot_compress() and ->cot_decompress(), always point to crypto_compress() and crypto_decompress(). Remove this pointless indirection, and just make crypto_comp_compress() and crypto_comp_decompress() be direct calls to what used to be crypto_compress() and crypto_decompress(). Also remove the unused function crypto_comp_cast(). Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
