[PATCH/RFC,4/5] usb: renesas_usbhs: change arguments of dma_map_ctrl()

Commit Message

Yoshihiro Shimoda April 5, 2016, 9:15 a.m. UTC

In near the future, since usbhsg_dma_map_ctrl() needs DMA device
structure, this patch changes arguments of dma_map_ctrl() to give
such data. (This patch is only change the argument.)
