      crypto: chacha20 - fix handling of chunked input · 4de43726
      Ard Biesheuvel authored
      Commit 9ae433bc ("crypto: chacha20 - convert generic and x86 versions
      to skcipher") ported the existing chacha20 code to use the new skcipher
      API, and introduced a bug along the way. Unfortunately, the tcrypt tests
      did not catch the error, and it was only found recently by Tobias.
      Stefan kindly diagnosed the error, and proposed a fix which is similar
      to the one below, with the exception that 'walk.stride' is used rather
      than the hardcoded block size. This does not actually matter in this
      case, but it's a better example of how to use the skcipher walk API.
