staging: comedi: change comedi_alloc_subdevice_minor parameters

`comedi_alloc_subdevice_minor()` doesn't really need a parameter pointing to a `struct comedi_device` as it can get this information from the parameter pointing to a `struct comedi_subdevice`. Just pass the subdevice parameter. Signed-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
