  Message : Create a new DeviceImpl each time one is requested from a DisplayImpl. This makes sure that the Device to DeviceImpl ratio is always 1:1 and avoids any potential double-deletion or unexpected deletion of DeviceImpl objects. BUG=742034 Change-Id: I778068ccd09b7478d3683123456062b94be242a1 Reviewed-on: https://chromium-review.googlesource.com/854627 Commit-Queue: Geoff Lang <geofflang@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org> Reviewed-by: Yuly Novikov <ynovikov@chromium.org>
