Subject: [PATCH 19/31] FW_LOADER: fix kconfig dependency warning on HOTPLUG

From: Randy Dunlap <randy.dunlap@...cle.com>

Fix kconfig dependency warning for FW_LOADER.

Lots of drivers select FW_LOADER without bothering to depend on
HOTPLUG and/or without selecting HOTPLUG.  A kernel builds fine
when FW_LOADER is enabled, whether HOTPLUG is enabled or not, and
a kernel config file (make oldconfig) is not changed by this patch.
(Yes, drivers/base/firmware_class.c uses interfaces from linux/kobject.h,
which does have some CONFIG_HOTPLUG dependencies, but this patch does
not change that.)
