[PATCH 0/4] usb: renesas_usbhs: fixes this driver in gadget mode

[Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>]

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.
