Subject: [Bluez PATCH v8 02/13] core: add device callbacks to adapter driver
Date: Tue,  3 Aug 2021 16:22:26 +0800	[thread overview]
Message-ID: <20210803161319.Bluez.v8.2.Iee308dd18bfdfd3dae9e343e78b3942ee462314f@changeid> (raw)
In-Reply-To: <20210803082237.723766-1-howardchung@google.com>

From: Yun-Hao Chung <howardchung@chromium.org>

This adds the following callbacks to btd_adapter_driver.

device_added:	 called when a device is added to the adapter
device_removed:	 called when a device is removed from the adapter
device_resolved: called when all services of the device have been
				 resolved.
---

Changes in v8:
- Add device_resolved.
- Remove space before function pointer arguments.
