Subject: [for-linus][PATCH 15/17] tools/bootconfig: Fix to return 0 if succeeded to show the bootconfig

From: Masami Hiramatsu <mhiramat@...nel.org>

Fix bootconfig to return 0 if succeeded to show the bootconfig
in initrd. Without this fix, "bootconfig INITRD" command
returns !0 even if the command succeeded to show the bootconfig.
