Subject: [Bluez PATCH v6 05/13] core: add device_added and device_removed to adapter driver
Date: Thu, 29 Jul 2021 20:27:43 +0800 [thread overview]
Message-ID: <20210729202648.Bluez.v6.5.Iee308dd18bfdfd3dae9e343e78b3942ee462314f@changeid> (raw)
In-Reply-To: <20210729122751.3728885-1-howardchung@google.com>
From: Yun-Hao Chung <howardchung@chromium.org>
This adds device_added and device_removed to btd_adapter_driver so that
a driver can get notification when device is added or removed.
