Subject: [PATCH 2/2] usb serial gadget: no TTY hangup on USB disconnect [WIP]
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We may want to maintain the TTY over USB disconnects.
This is useful when we have a terminal console to a host which
power-cycles or for other reasons resets the USB host controller.
