   4 Subject: [PATCH 02/15] crypto: skcipher - remove useless setting of type flags
   5
   6 Some skcipher algorithms set .cra_flags = CRYPTO_ALG_TYPE_SKCIPHER.  But
   7 this is redundant with the C structure type ('struct skcipher_alg'), and
   8 crypto_register_skcipher() already sets the type flag automatically,
   9 clearing any type flag that was already there.  Apparently the useless
  10 assignment has just been copy+pasted around.
  11
  12 So, remove the useless assignment from all the skcipher algorithms.
  13
  14 This patch shouldn't change any actual behavior.
