[PATCH] usb: dwc3: gadget: Clear DEP flags after stop transfers in ep disable

From: Wesley Cheng <hidden>
Date: 2021-03-24 18:31:54
Also in: lkml
Subsystem: designware usb3 drd ip driver, the rest, usb subsystem · Maintainers: Thinh Nguyen, Linus Torvalds, Greg Kroah-Hartman

Ensure that dep->flags are cleared until after stop active transfers
is completed.  Otherwise, the ENDXFER command will not be executed
during ep disable.

Fixes: f09ddcfcb8c5 ("usb: dwc3: gadget: Prevent EP queuing while stopping transfers")
