Subject: staging: comedi: ni_pcidio: use cfc_handle_events()
X-Git-Tag: v4.14-rc1~7811^2~278
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a4ccee260caee624ffc6c61327ed78ea19d08e3a;p=platform%2Fkernel%2Flinux-rpi.git

staging: comedi: ni_pcidio: use cfc_handle_events()

Use the comedi_fc helper function instead of duplicating the code.

In the Kconfig, COMEDI_NI_PCIDIO selects COMEDI_FC indirectly by
selecting COMEDI_MITE which selects COMEDI_FC.
