Subject: [PATCH 02/12] staging: comedi: das08_cs: consolidate the init and exit functions

The register/unregister of the pcmcia driver is done in 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.
