Subject[PATCH v4 8/8] usb: dwc3: Check MISSED ISOC bit only for ISOC endpoints
Date
When streaming is enabled on BULK endpoints and LST bit is set
observed MISSED ISOC bit set in event->status for BULK ep. Since
this bit is only valid for isocronous endpoints, changed the code
to check for isocrnous endpoints when MISSED ISOC bit is set.
