Subject: [PATCH 2/2] z2ram: Delete a jump label in z2_init()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 11 Dec 2015 18:48:14 +0100

This issue was detected by using the Coccinelle software.

* Let us return directly if a call of the function "register_blkdev" failed.

* Remove the jump label "err" then.
