Hi,
I am trying to implement a nor driver for a Intel strata flash chip on Linux
2.6.14. My problem is that the driver code is not calling the probe
function. My declarations are as follows:
static struct device_driver mm6p_flash_driver = {
.name = "mm6p_flash",
.bus = &platform_bus_type,
.probe = mm6p_flash_probe,
.remove = mm6p_flash_remove,
};
static int __init mm6p_flash_init(void)
{
printk("$$$$$in mm6p_flash_init$$$$$$$$$$\n");
return driver_register(&mm6p_flash_driver);
}
module_init(mm6p_flash_init);
The mm6p_flash_init is called, but the mm6p_flash_probe is not being
invoked. My system configuration flags are as follows:

What could be the problem?
