A warning is found by the static code analysis tool:
  "Identical condition 'err', second condition is always false"

Fix this by adding return value of skcipher_walk_done().

Fixes: 67cfa5d3b721 ("crypto: arm64/aes-neonbs - implement ciphertext stealing for XTS")

v2 -> v3:
 - add "Acked-by:"

v1 -> v2:
 - update the subject and comment
 - add return value of skcipher_walk_done()

Please don't send the exact same patch twice, and when you feel the
need to do so, just ask instead whether your patch was received or
not.

I'm sure Herbert will pick it up shortly.
