Subject[PATCH 2/5] usb: dwc3: gadget: Force sending delayed status during soft disconnect
Date
If any function drivers request for a delayed status phase, this leads to a
SETUP transfer timeout error, since the function may take longer to process
the DATA stage. This eventually results in end transfer timeouts, as there
is a pending SETUP transaction.
