Auto-configuration (auto-attachment) of USB and PCI comedi devices all goes through `comedi_auto_config_helper()`. That is a good place to set the comedi device's `hw_dev` pointer to the hardware `struct device` via a call to `comedi_set_hw_dev(comedi_device, hardware_device)` as it may obviate the need for the low-level comedi driver to make this call.
