Subject: [PATCH] Staging: comedi: addi-data: remove unnecessary variable initializations in hwdrv_apci035.c

Nearly every variable in hwdrv_apci035.c is initialized to 0 when it is
declared, and then set to some other value before ever being used.  As
such, we can remove all of these initializations.  They are accomplishing
nothing.
