[PATCH 5.6 39/71] usb: dwc3: gadget: Dont clear flags before transfer ended

[Greg Kroah-Hartman]

From: Thinh Nguyen <Thinh.Nguyen@xxxxxxxxxxxx>

commit a114c4ca64bd522aec1790c7e5c60c882f699d8f upstream.

We track END_TRANSFER command completion. Don't clear transfer
started/ended flag prematurely. Otherwise, we'd run into the problem
with restarting transfer before END_TRANSFER command finishes.

Fixes: 6d8a019614f3 ("usb: dwc3: gadget: check for Missed Isoc from event status")
