Subject: [PATCH 06/10] md/dm-crypt: Delete an unnecessary variable
 initialisation in crypt_set_key()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 28 Sep 2016 15:24:13 +0200

The local variable "r" will be set to an appropriate value a bit later.
Thus omit the explicit initialisation at the beginning.
