I forgot to write it, sorry. I was going to explain the decision to leave
the bus matching up to the driver.

The modprobe, rmmod, modprobe sequence was tested. But I think that isn't
what you meant.
Are you saying there is a missing NULL check? That is,
static int nubus_device_remove(struct device *dev)
{
struct nubus_driver *ndrv = to_nubus_driver(dev->driver);
int err = -ENODEV;
- if (ndrv->remove)
+ if (dev->driver && ndrv->remove)
err = ndrv->remove(to_nubus_board(dev));
return err;
}
Anyway, I will revise the patch and test the unbind operation on a device
not already bound.
Thanks for your feedback.
