Hi,

Is there any feasible way to dereference a pointer inside
__mod_*_device_table which points to a string? 

e.g.:

include/linux/mod_devicetable.h:

struct pcmcia_device_id {
	...
	const char * prod_id;
	...
}

drivers/some/driver.c:

static struct pcmcia_device_id some_ids[] = {
	{.prod_id = "some device string", ...},
	...
}
MODULE_DEVICE_TABLE(some_ids);


scripts/mod/file2alias.c:

do_pcmcia_entry (..., struct pcmcia_device_id *id, ...) 
{
	const char *tmp = id->prod_id + SOME_MAGIC_VALUE;
}


Thanks,
	Dominik
