Fix compile warnings
This patch fixes compile warnings that appear with newer compilers. The solution applied is only to remove the warnings, but it doesn't always solve the problem in the best way. It assumes that the problem will never happen, as the previous code assumed. Change-Id: I6e8470d6c2e2dbd3bd7d324b5fd2f92ffdc3d6ec updates: bz#1193929 Signed-off-by: Xavi Hernandez <xhernandez@redhat.com>
