The extcon core already provides the extcon_register_notifier() function in order to register the notifier block which is used to monitor the state change for the specific external connector such as EXTCON_USB, EXTCON_USB_HOST and so on. The extcon consumer uses the this function. The extcon consumer might need to monitor the all supported external connectors from the extcon device. In this case, The extcon consumer should have each notifier_block structure for each external connector. This patch adds the new extcon_register_notifier_all() function that extcon consumer is able to monitor the state change of all supported external connectors by using only one notifier_block structure. - List of new added functions: int extcon_register_notifier_all(struct extcon_dev *edev, struct notifier_block *nb); int extcon_unregister_notifier_all(struct extcon_dev *edev, struct notifier_block *nb); int devm_extcon_register_notifier_all(struct device *dev, struct extcon_dev *edev, struct notifier_block *nb); void devm_extcon_unregister_notifier_all(struct device *dev, struct extcon_dev *edev, struct notifier_block *nb); Suggested-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Tested-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Hans de Goede <hdegoede@redhat.com> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
