But +this is redundant with the C structure type ('struct skcipher_alg'), and +crypto_register_skcipher() already sets the type flag automatically, +clearing any type flag that was already there. Apparently the useless +assignment has just been copy+pasted around. + +So, remove the useless assignment from all the skcipher algorithms. + +This patch shouldn't change any actual behavior. + +Signed-off-by: Eric Biggers <ebiggers@google.com> +Acked-by: Gilad Ben-Yossef <gilad@benyossef.com> +Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> +--- + drivers/crypto/amcc/crypto4xx_core.c | 18 ++++++------------ + 1 file changed, 6 insertions(+), 12 deletions(-) + +--- a/drivers/crypto/amcc/crypto4xx_core.c ++++ b/drivers/crypto/amcc/crypto4xx_core.c +@@ -1132,8 +1132,7 @@ static struct crypto4xx_alg_common crypt + .cra_name = "cbc(aes)", + .cra_driver_name = "cbc-aes-ppc4xx", + .cra_priority = CRYPTO4XX_CRYPTO_PRIORITY, +- .cra_flags = CRYPTO_ALG_TYPE_SKCIPHER | +- CRYPTO_ALG_ASYNC | ++ .cra_flags = CRYPTO_ALG_ASYNC | + CRYPTO_ALG_KERN_DRIVER_ONLY, + .cra_blocksize = AES_BLOCK_SIZE, + .cra_ctxsize = sizeof(struct crypto4xx_ctx), +@@ -1153,8 +1152,7 @@ static struct crypto4xx_alg_common crypt + .cra_name = "cfb(aes)", + .cra_driver_name = "cfb-aes-ppc4xx", + .cra_priority = CRYPTO4XX_CRYPTO_PRIORITY, +- .cra_flags = CRYPTO_ALG_TYPE_SKCIPHER | +- CRYPTO_ALG_ASYNC | ++ .cra_flags = CRYPTO_ALG_ASYNC | + CRYPTO_ALG_KERN_DRIVER_ONLY, + .cra_blocksize = AES_BLOCK_SIZE, + .cra_ctxsize = sizeof(struct crypto4xx_ctx), +@@ -1174,8 +1172,7 @@ static struct crypto4xx_alg_common crypt + .cra_name = "ctr(aes)", + .cra_driver_name = "ctr-aes-ppc4xx", + .cra_priority = CRYPTO4XX_CRYPTO_PRIORITY, +- .cra_flags = CRYPTO_ALG_TYPE_SKCIPHER | +- CRYPTO_ALG_NEED_FALLBACK | ++ .cra_flags = CRYPTO_ALG_NEED_FALLBACK | + CRYPTO_ALG_ASYNC | + CRYPTO_ALG_KERN_DRIVER_ONLY, + .cra_blocksize = AES_BLOCK_SIZE, +@@ -1196,8 +1193,7 @@ static struct crypto4xx_alg_common crypt + .cra_name = "rfc3686(ctr(aes))", + .cra_driver_name = "rfc3686-ctr-aes-ppc4xx", + .cra_priority = CRYPTO4XX_CRYPTO_PRIORITY, +- .cra_flags = CRYPTO_ALG_TYPE_SKCIPHER | +- CRYPTO_ALG_ASYNC | ++ .cra_flags = CRYPTO_ALG_ASYNC | + CRYPTO_ALG_KERN_DRIVER_ONLY, + .cra_blocksize = AES_BLOCK_SIZE, + .cra_ctxsize = sizeof(struct crypto4xx_ctx), +@@ -1217,8 +1213,7 @@ static struct crypto4xx_alg_common crypt + .cra_name = "ecb(aes)", + .cra_driver_name = "ecb-aes-ppc4xx", + .cra_priority = CRYPTO4XX_CRYPTO_PRIORITY, +- .cra_flags = CRYPTO_ALG_TYPE_SKCIPHER | +- CRYPTO_ALG_ASYNC | ++ .cra_flags = CRYPTO_ALG_ASYNC | + CRYPTO_ALG_KERN_DRIVER_ONLY, + .cra_blocksize = AES_BLOCK_SIZE, + .cra_ctxsize = sizeof(struct crypto4xx_ctx), +@@ -1237,8 +1232,7 @@ static struct crypto4xx_alg_common crypt + .cra_name = "ofb(aes)", + .cra_driver_name = "ofb-aes-ppc4xx", + .cra_priority = CRYPTO4XX_CRYPTO_PRIORITY, +- .cra_flags = CRYPTO_ALG_TYPE_SKCIPHER | +- CRYPTO_ALG_ASYNC | ++ .cra_flags = CRYPTO_ALG_ASYNC | + CRYPTO_ALG_KERN_DRIVER_ONLY, + .cra_blocksize = AES_BLOCK_SIZE, + .cra_ctxsize = sizeof(struct crypto4xx_ctx), |
