+Subject: usb: dwc3: fix TRB completion when multiple TRBs are started
+
+From: Felipe Balbi <balbi@ti.com>
+
+commit 0b93a4c838fa10370d72f86fe712426ac63804de upstream.
+
+After commit 2ec2a8be (usb: dwc3: gadget:
+always enable IOC on bulk/interrupt transfers)
+we created a situation where it was possible to
+hang a bulk/interrupt endpoint if we had more
+than one pending request in our queue and they
+were both started with a single Start Transfer
+command.
+
+The problems triggers because we had not enabled
+Transfer In Progress event for those endpoints
+and we were not able to process early giveback
+of requests completed without LST bit set.
+
+Fix the problem by finally enabling Xfer In Progress
+event for all endpoint types, except control.
+
+Fixes: 2ec2a8be (usb: dwc3: gadget: always
+       enable IOC on bulk/interrupt transfers)
