From 7691993c2b290dfedfb08a8eaa8cf7d5c6573fcb Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Tue, 11 Feb 2014 09:12:27 +0100 Subject: s390x/ipl: Improved code indentation in s390_ipl_init() The indentation of the code in s390_ipl_init() can be simplified a little bit by removing superfluous else-statements.
