Subject[PATCH 2/5] s390/pci: Return directly after a failed clp_alloc_block() in clp_normal_command()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 21 Jan 2017 17:56:40 +0100

* Return directly after a call of the function "clp_alloc_block"
failed here.

* Delete the jump label "out" which became unnecessary with
this refactoring.
