Because of the usb (*probe) and comedi (*attach) disconnect, the struct
slot_dt9812 is used to pass the device data between the usb_driver and
the comedi_driver. The variable 'comedi' in this struct is used during
the comedi (*attach) to indicate if a slot is currently being used.

For aesthetic reasons, rename the variable to 'devpriv' since that is
what is actually saved in the pointer.
