From: Krzysztof Kozlowski <krzk@kernel.org> [ Upstream commit c9570d4a5efd04479b3cd09c39b571eb031d94f4 ] Add stubs for extcon_register_notifier_all() function for !CONFIG_EXTCON case. This is useful for compile testing and for drivers which use EXTCON but do not require it (therefore do not depend on CONFIG_EXTCON).
