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

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.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.
