Subject: [PATCH 06/14] staging: comedi: daqboard2000: rename register offset macros
Rename the macros defining register offsets to avoid CamelCase, and to
use namespace associated with the driver.
Signed-off-by: Ian Abbott <abbotti@....co.uk>
---
Other CamelCase issues in this patch will be dealt with by later
patches in the series.
