Subject: [Qemu-devel] [PATCH 7/7] s390x/kvm: Remove redundant return code
Date: Mon, 15 Jul 2013 21:57:45 +0200	[thread overview]
Message-ID: <1373918265-20172-8-git-send-email-borntraeger@de.ibm.com> (raw)
In-Reply-To: <1373918265-20172-1-git-send-email-borntraeger@de.ibm.com>

From: Thomas Huth <thuth@linux.vnet.ibm.com>

Removed the redundant return code statement from handle_instruction() - it
always returned 0 and never reports any errors to its caller, since errors
from the sub-functions are already reported via program exceptions instead.
