If we tested this driver as gadget and g_ncm driver using iperf,
some issues below happened:
- Oops happened.
- A transaction didn't finish in PIO mode.
- A transaction didn't finish in DMA mode if the "zero" flag is set.
- The driver didn't cancel a transaction if dequeue() is called.
This patch series fixes them. If possible, they would like to be
merged to v3.17.
This patch series is based on Greg's usb.git / usb-linus branch.
