Subject: [PATCH 4/6] crypto-caamhash: Return a value directly in
 caam_hash_cra_init()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 15 Sep 2016 14:56:12 +0200

* Return a value at the end without storing it in an intermediate variable.

* Delete the local variable "ret" which became unnecessary with
  this refactoring.
