Subject[PATCH 2/2 v2] Staging: comedi: addi-data: remove unnecessary variable initializations in hwdrv_apci1564.c
Date
A handful of variables here were being initialized to 0 upon declaration,
however they are always then set to another value before their first use,
so initialization here is useless and we can remove it.

2: no content change; redone and resent after PATCH 1/2 changed to ensure
clean applying.
