[linuxdc-dev]do_map_probe

[Adrian M. <ad...@mc...>]

This fails on my DC (reworked code shown below):

static int dc_flashmap_connect(struct maple_driver_data *d)
{
  printk("Regitering VMU Flash mapping and loading VMU Flash driver\n");
	/* Look for the flash */
	if (!vmu_flash_mtd) vmu_flash_mtd = do_map_probe("cfi", &vmu_flash_map);

	/* See if it's valid */
	if (!vmu_flash_mtd) {
		printk(KERN_ERR "Failed to setup flash map\n");
		return -ENXIO;
	}
	printk("VMU FLASH: mapping successful\n");

	vmu_flash_mtd->module = THIS_MODULE;

	/* Register with MTD */
	add_mtd_device(vmu_flash_mtd);
  
  return 0;
}

It appears to run modprobe - can someone explain to me what it does. I haven't 
read the source, I admit. But I have googled and I am none the wiser.
