From 19e5d9c0d2194b4b47189cbec2921cbf72b0bd1c Mon Sep 17 00:00:00 2001 From: Henry Nestler Date: Wed, 6 Dec 2006 20:37:45 -0800 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.
