Subject: [PATCH 3.14] power_supply: don't export power_supply_notifier

From: Johannes Berg <johannes.berg@...el.com>

Since there are registration/unregistration functions and the
invocation is in the core code, there's no need to export the
notifier chain head, make it static instead.

Signed-off-by: Johannes Berg <johannes.berg@...el.com>

This should probably go into 3.14 so it's not exported in the release.
