Subject: Re: [PATCH 0/3] Bluetooth: Emit events for suspend/resume

Hi Marcel,

Please review this patch. A newer series for how the controller resume
event will be used is available at
https://patchwork.kernel.org/project/bluetooth/list/?series=334811

Besides usage in bluez, these events will also make debugging and
testing suspend/resume for Bluez easier (i.e. finding spurious wakes
due to BT in suspend stress tests, asserting that wakeup from peers
occurred as expected in tests)

Abhishek
