The driver initialization problem is solved by this patch on my S3C2416 based
board. Nevertheless, I didn’t have the time yet to test an actual SPI device
connected to the bus.
BTW, I think the two debug messages at the end of the s3c64xx_spi_probe() routine
should be promoted from dev_dbg to dev_info in order to be shown on a normal
kernel boot.
