| Subject: [PATCH] usb: dwc3: gadget: Don't clear flags before transfer ended |
| |
| 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. |
