This doesn't build:

drivers/spi/spi-s3c64xx.c: In function 's3c64xx_get_slave_ctrldata':
drivers/spi/spi-s3c64xx.c:1023: error: 'sdd' undeclared (first use in this function)
drivers/spi/spi-s3c64xx.c:1023: error: (Each undeclared identifier is reported only once
drivers/spi/spi-s3c64xx.c:1023: error: for each function it appears in.)
