spi/s3c64xx: Fix compilation warning
Fix compilation warning by typecasting the tx_buf pointer. [I'm not thrilled with resorting to a cast; but I cannot see a better way to go about this. I don't want to drop the const from struct spi_transfer ~~glikely] Signed-off-by: Jassi Brar <jassi.brar@samsung.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
