Subject: [PATCH 04/31] staging: comedi: ni_daq_700: consolidate the init and exit functions

The register/unregister of the pcmcia driver is done is separate
functions that are called by the module_{init,exit} routines.
Simplify the code a bit by moving the register/unregister into
the module_{init,exit} routines.
