[PATCH 30/31] staging: comedi: quatech_daqp_cs: use cfc_handle_events()

[H Hartley Sweeten <hsweeten@xxxxxxxxxxxxxxxxxxx>]

Use the comedi_fc helper function to automatically call the subdevice
(*cancel) function when needed and call comedi_event().

Update the Kconfig so that COMEDI_QUATECH_DAQP_CS selects COMEDI_FC.
