Subject: crypto: cryptd - Remove unnecessary skcipher_request_zero
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e16dda2b69ba36c01522735221f08e9dd8f438d3;p=linux.git

crypto: cryptd - Remove unnecessary skcipher_request_zero

Previously the child skcipher request was stored on the stack and
therefore needed to be zeroed.  As it is now dynamically allocated
we no longer need to do so.
