From: Chaoyi Chen <[email protected]> The DRM may want to register a notifier on the typec bus to know when a typec altmode device is added, and distinguish between different types of typec altmode device.
Export these things. Signed-off-by: Chaoyi Chen <[email protected]> --- Changes in v11: - Also export typec bus. - Add more detailed comments.
