From cd17e153af499c74d7e347c8ad7eab273f55f20b Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Fri, 15 Jan 2016 14:52:59 +0100 Subject: [PATCH] s390: remove superfluous memblock_alloc() return value checks memblock_alloc() and memblock_alloc_base() will panic on their own if they can't find free memory. Therefore remove some pointless checks.
