Subject: crypto: mcryptd - pass through absence of ->setkey()
From: Eric Biggers <ebiggers@google.com>
commit fa59b92d299f2787e6bae1ff078ee0982e80211f upstream.
When the mcryptd template is used to wrap an unkeyed hash algorithm,
don't install a ->setkey() method to the mcryptd instance. This change
is necessary for mcryptd to keep working with unkeyed hash algorithms
once we start enforcing that ->setkey() is called when present.

Nope, this breaks the build, now dropped :(
