Something passed a null device pointer to dev_printk().

I think that hso_create_rfkill() is the culprit here (and has been inlined into hso_create_net_device()). It's using hso_dev->dev as the first argument to dev_err() and it doesn't look like that field is initialised except by kzalloc. At a guess, it should be using &hso_dev->usb->dev.
