Looks like drivers/mmc/host/omap.c is using platform_driver_probe() instead of platform_driver_register(). Add the probe hook to the platform_driver structure and change it to call platform_driver_register() and it should work. Don't forget to change mmc_omap_probe from __init to __devinit. g. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
