I actually forgot to formulate my question: why module's refcount is not increased when somebody opens a sysfs file which belongs to this module? How to withstan to an unexpected module unload?

Thanks.
I see this code drivers/base/core.c, device_add().

if (dev->driver)
dev->uevent_attr.attr.owner = dev->driver->owner;

I assume it is expected that I must have a driver structure. But I don't. Why do I have to?
