usb: renesas_usbhs: modify data transfer interrupt
On current driver, overall data transfer method was implemented in fifo.c, but its interrupt which is member of packet queue control was still in mod_gadget.c. This patch move it into fifo.c. By this patch, the packet/fifo control is independent from mod_gadget. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
