Can this be moved to mmc_blk_probe(), perhaps? Regards, Simon

Every time a mmc bus/port is scanned and a new device is detected, we want to call device_probe() as it will give us a chance to run additional post-processings for some purposes. In particular, support for creating partitions on a device will be added.
