usb: dwc3: fix TRB completion when multiple TRBs are started
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) Cc: <stable@vger.kernel.org> # v3.14+ Reported-by: Pratyush Anand <pratyush.anand@st.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
