6.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Thinh Nguyen <Thinh.Nguyen@xxxxxxxxxxxx> commit 5d2fb074dea289c41f5aaf2c3f68286bee370634 upstream. The driver cannot issue the End Transfer command to the SETUP transfer. Don't clear DWC3_EP_TRANSFER_STARTED flag to make sure that the driver won't send Start Transfer command again, which can cause no-resource error. For example this can occur if the host issues a reset to the device.
