Subject: [PATCH] drivers/crypto/nx: saves chaining value from co-processor
Date: Fri, 02 Aug 2013 15:58:10 -0500	[thread overview]
Message-ID: <1375477090.32477.10.camel@what-is-leg> (raw)

The chaining value from co-processor was not being saved. This value is
needed because it is used as the IV, for example by cts i.e.
cts(cbc(aes)).
