Subject: staging: comedi: addi_apci_035: remove unnecessary subdevice initialization
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=8d3e0bf092309808f715fd703bed2719eb77b982;p=deliverable%2Flinux.git

staging: comedi: addi_apci_035: remove unnecessary subdevice initialization

The subdevices that don't initialize any of the callbacks don't really
exist. Remove the unnecessary initialzation and just set the type to
COMEDI_SUBD_UNUSED.
