[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. Signed-off-by: Henry Nestler <henry.ne@arcor.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
