Subject: crypto: skcipher - Use tmpl->create
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=56e34378bbbb7af21cf73d98a92c0411386e091c;p=openwrt%2Fstaging%2Fblogic.git

crypto: skcipher - Use tmpl->create

Newer templates use tmpl->create and have a NULL tmpl->alloc.  So
we must use tmpl->create if it is set.
