extcon: Add resource-managed functions to register extcon notifier
This patch adds the resource-managed functions for register/unregister
the extcon notifier with the id of each external connector. This function
will make it easy to handle the extcon notifier.
- int devm_extcon_register_notifier(struct device *dev,
struct extcon_dev *edev, unsigned int id,
struct notifier_block *nb);
- void devm_extcon_unregister_notifier(struct device *dev,
struct extcon_dev *edev, unsigned int id,
struct notifier_block *nb);
