From fb6aa25009ff7c8ec65673d5a34d7191dc6c5894 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 7 Mar 2014 17:31:45 -0700 Subject: [PATCH] staging: comedi: quatech_daqp_cs: use cfc_handle_events() 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.
