Subject: [Qemu-devel] [PULL 7/9] s390x/ipl: Improved code indentation in s390_ipl_init()
Date: Tue,  3 Feb 2015 14:08:46 +0100	[thread overview]
Message-ID: <1422968928-9710-8-git-send-email-cornelia.huck@de.ibm.com> (raw)
In-Reply-To: <1422968928-9710-1-git-send-email-cornelia.huck@de.ibm.com>

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

The indentation of the code in s390_ipl_init() can be simplified
a little bit by removing superfluous else-statements.
