drm/bridge: dw-hdmi: export hotplug functions
From: Algea Cao <algea.cao@...> Date: Sat, 30 Sep 2017 09:44:21 +0800
Commit-Message
External phys may not provide their own hotplug-related routines but instead rely on the dw-hdmi ones. Export these functions so that external hdmi-phys can use them if necessary. Signed-off-by: Algea Cao <algea.cao@...> [export all 3 hotplug-related functions] Signed-off-by: Heiko Stuebner <heiko@...>
