If anyone has any objections, please let me know. ------------------ From: Eli Cohen commit dbaaff2a2caa03d472b5cc53a3fbfd415c97dc26 upstream. When an internal error condition is detected, make sure to set the device inactive after dispatching the event so ULPs can get a notification of this event.
