Did you register a suitable platform_device with the same name!?

Something like

struct platform_device foo_device = {
        .name           = "mm6p_flash",
        .id             = -1,
        .dev            = {
                                .platform_data          = &foo_data,
        },
        .resource       = foo_resources,
        .num_resources  = ARRAY_SIZE(foo_resources),
};

platform_device_register(&foo_device);

Usually in your board specific startup files.

driver and device are matched by name! So if there's no device "mm6p_flash"
registered, then there's no need to call probe in driver "mm6p_flash".

Ok?
