Each event in an event ring describes the TRE whose completion caused the event. Currently, every event ring is dedicated to a single channel, so the channel is easily derived from the event ring. An event ring can actually be shared by more than one channel though, and to distinguish events for one channel from another, the event structure contains a field indicating which channel the event is associated with. In gsi_event_trans(), use the channel ID in an event to determine which channel the event is for. This makes the channel pointer now passed to that function irrelevant; pass the GSI pointer to that function instead. And although it shouldn't happen, warn if an event arrives that records a channel ID that's not in use, or if the event does not have a transaction associated with it. Signed-off-by:
