Subject: crypto: marvell/cesa - use memcpy_and_pad in mv_cesa_ahash_export
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=914b0c68d4decebe52b31929f89364de32d0156e;p=thirdparty%2Fkernel%2Fstable.git

crypto: marvell/cesa - use memcpy_and_pad in mv_cesa_ahash_export

Replace memset() followed by memcpy() with memcpy_and_pad() to simplify
the code and to write to 'cache' only once.
