crypto: sun8i-ss - remove redundant memzero_explicit()
Remove redundant memzero_explicit() in sun8i_ss_cipher() before calling kfree_sensitive(). kfree_sensitive() will zero the memory with memzero_explicit(). Fixes: 453431a54934 ("mm, treewide: rename kzfree() to kfree_sensitive()") Signed-off-by: Denis Efremov <efremov@linux.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
