X-Git-Tag: io_uring-5.10-2020-10-20~106^2~147

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()")
