Subject: [PATCH 2/2] init/Kconfig: use if/endif to surround the EXPERT menu
kconfig symbols
From: Randy Dunlap <randy.dunlap@...cle.com>
Surround the EXPERT menu with "if EXPERT" and "endif" so that it
is forced to stay as one unit. Hopefully this will help to prevent
it being broken in the future.
