| Subject: usb: dwc3: gadget: Clear wait flag on dequeue |
| |
| From: Thinh Nguyen <Thinh.Nguyen@synopsys.com> |
| |
| commit a5c7682aaaa10e42928d73de1c9e1e02d2b14c2e upstream. |
| |
| If an active transfer is dequeued, then the endpoint is freed to start a |
| new transfer. Make sure to clear the endpoint's transfer wait flag for |
| this case. |
