| Subject: [PATCH] usb: dwc3: gadget: Fix logical condition |
| |
| commit 8c7d4b7b3d43c54c0b8c1e4adb917a151c754196 upstream. |
| |
| This patch corrects the condition to kick the transfer without |
| giving back the requests when either request has remaining data |
| or when there are pending SGs. The && check was introduced during |
| spliting up the dwc3_gadget_ep_cleanup_completed_requests() function. |
| |
| Fixes: f38e35dd84e2 ("usb: dwc3: gadget: split dwc3_gadget_ep_cleanup_completed_requests()") |
