[ Upstream commit c9570d4a5e ]
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).
Fixes: 815429b39d ("extcon: Add new extcon_register_notifier_all() to monitor all external connectors")
