From 19e5d9c0d2194b4b47189cbec2921cbf72b0bd1c Mon Sep 17 00:00:00 2001
From: Henry Nestler <henry.ne@arcor.de>

Subject: [PATCH] [PATCH] initrd: remove unused false condition for
initrd_start
After LOADER_TYPE && INITRD_START are true, the short if-condition
for INITRD_START can never be false.
Remove unused code from the else condition.
