[PATCH 30/36] staging: comedi: cb_pcidas: change dac bit enums into defines

From: H Hartley Sweeten
Date: Tue Jun 26 2012 - 21:08:19 EST


The 'bits' for the DAC_CSR register are currently defined as
enums. All the other registers use defines for the bit definitions.
Change the dac bit enums to defines to follow the other registers.
