Pawel Laszczak 1301c7b9f7 usb: cdns3: remove fetched trb from cache before dequeuing ... After doorbell DMA fetches the TRB. If during dequeuing request driver changes NORMAL TRB to LINK TRB but doesn't delete it from controller cache then controller will handle cached TRB and packet can be lost. The example scenario for this issue looks like: 1. queue request - set doorbell 2. dequeue request 3. send OUT data packet from host 4. Device will accept this packet which is unexpected 5. queue new request - set doorbell 6. Device lost the expected packet. By setting DFLUSH controller clears DRDY bit and stop DMA transfer.
