staging: comedi: comedi_usb: allow comedi usb drivers to pass a 'context'
Allow the comedi usb drivers to pass a 'context' from their (*probe) functions to the comedi core's comedi_usb_auto_config(). This 'context' is then passed to comedi_auto_config() and then to the comedi_driver's (*auto_attach).
