From 58f386560a68dd98bd6744a28fc853eef11faebe Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Mon, 27 Jun 2016 20:03:39 +0900 Subject: 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); Signed-off-by: Chanwoo Choi --- include/linux/extcon.h | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) (limited to 'include/linux') diff --git a/include/linux/extcon.h b/include/linux/extcon.h index 1b2c8b6809cc..7bf530f3f4f5 100644 --- a/include/linux/extcon.h +++ b/include/linux/extcon.h @@ -182,6 +182,12 @@ extern int extcon_register_notifier(struct extcon_dev *edev, unsigned int id, struct notifier_block *nb); extern int extcon_unregister_notifier(struct extcon_dev *edev, unsigned int id, struct notifier_block *nb); +extern int devm_extcon_register_notifier(struct device *dev, + struct extcon_dev *edev, unsigned int id, + struct notifier_block *nb); +extern void devm_extcon_unregister_notifier(struct device *dev, + struct extcon_dev *edev, unsigned int id, + struct notifier_block *nb); /* * Following API get the extcon device from devicetree. @@ -273,6 +279,17 @@ static inline int extcon_unregister_notifier(struct extcon_dev *edev, return 0; } +static inline int devm_extcon_register_notifier(struct device *dev, + struct extcon_dev *edev, unsigned int id, + struct notifier_block *nb) +{ + return -ENOSYS; +} + +static inline void devm_extcon_unregister_notifier(struct device *dev, + struct extcon_dev *edev, unsigned int id, + struct notifier_block *nb) { } + static inline struct extcon_dev *extcon_get_edev_by_phandle(struct device *dev, int index) { -- cgit v1.2.3
