Subject: Atmel SPI master doesn't work in 3.9-rc8

Hi Nicolas,

I just tried 3.9-rc8 with my board. SPI doesn't work, since in spi.c in __spi_async() was inserted new checking that initiate now xfer->speed_hz:
		if (!xfer->speed_hz)
			xfer->speed_hz = spi->max_speed_hz;


And in atmel-spi.c there are another checking that allows SPI work only for speed_hz == 0:

		/* FIXME implement these protocol options!! */
		if (xfer->speed_hz) {
			dev_dbg(&spi->dev, "no protocol options yet\n");
			return -ENOPROTOOPT;
		}


Best regards,
Sergey
