Subject: [PATCH] rewrite the return method of static int
	s3c24xx_spi_setup(struct spi_device *spi) in
	drivers/spi/spi_s3c24xx.c 

rewrite the return method of static int 
s3c24xx_spi_setup(struct spi_device *spi) 
in drivers/spi/spi_s3c24xx.c 

reason:
s3c24xx_spi_setupxfer(spi, NULL) return 0 or -EINVAL, 
so here shoud return the ret,but only 0.
