+Subject: [PATCH] vhm: fix audio backend module handle ioreq incorrectly
+
+While we get all ioreq from vhm module, we need only handle those
+belongs us. Without this patch, audio backend take all ioreqs and mark
+them as completed which is not correct.
+Also, REQ_STATE_COMPLETE should be marked in acrn_ioreq_complete_request,
+so we needn't do that before it.
