[PATCH v3 2/5] Staging: comedi: addi-data: tidy up digital output register map defines in hwdrv_apci1564.c

From: Chase Southwood
Date: Fri Mar 07 2014 - 19:42:05 EST


This patch fixes the register map defines for the digital output registers
such that they are all the real offsets to each register, rather than a
mix of real offsets and adders to those offsets.

Further, some of the old defines were being used incorrectly in the
i_APCI1564_Reset() function. Upon swapping the old defines out for the
new ones in this function, their use has been corrected.

2: Simplified commit message, fixed indentation and whitespace damage.
I have test applied this patch, it should work now.

3: Fixed indentation (again)
