Subject: libcamera: camera_manager: Return a copy of the vector from cameras()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Making CameraManager::cameras() thread-safe requires returning a copy of
the cameras vector instead of a reference. This is also required for
hot-plugging support and is thus desirable.
