I looked into this and found that this comes from drivers/pcmcia/ds.c

There is a function get_device_info() which has a tree with label 
'found:'. This label is reached, then

if (first)
   node = p_dev->instance->dev;

sets node to 0 and function exits with

if (!node) {
   ret = -ENODEV;
   goto err_put;

Has anybody a hint what's wrong if p_dev->instance->dev is zero?

In my driver I set

socket.dev.dev = &omap_cf_device.dev;

with

static struct platform_device omap_cf_device = {
	.name = MODNAME,
	.id = 0,
};

In the driver omap_cf_device.dev isn't touched because in hd64465_ss.c 
hd64465_device.dev isn't set as well (?).

Thanks

Dirk
