crypto: scatterwalk - Check for same address in map_and_copy This patch adds a check for in scatterwalk_map_and_copy to avoid copying from the same address to the same address. This is going to be used for IV copying in AEAD IV generators. There is no provision for partial overlaps. This patch also uses the new scatterwalk_ffwd instead of doing it by hand in scatterwalk_map_and_copy. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
