[v4,8/8] usb: dwc3: Check MISSED ISOC bit only for ISOC endpoints

From: Anurag Kumar Vulisha <hidden>
Date: 2018-09-08 15:03:50
Also in: lkml
Subsystem: designware usb3 drd ip driver, the rest, usb subsystem · Maintainers: Thinh Nguyen, Linus Torvalds, Greg Kroah-Hartman

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.
