Cc: trivial@...nel.org
Subject: subj: [PATCH] initrd: Remove unused false condition for
initrd_start
From: Henry Nestler <henry.ne@...or.de>
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.
Signed-off-by: Henry Nestler <henry.ne@...or.de>

Grepped for all of these code style in all arch and changed here.
