[PATCH 1/3] Staging: comedi: addi-data: comment cleanup in hwdrv_apci035.c
From: Chase Southwood
Date: Fri Feb 21 2014 - 22:21:28 EST
This patch further cleans up the comments in hwdrv_apci035.c, converting
them to kernel style and removing some commented conditional statements
that are unused.
Signed-off-by: Chase Southwood <chase.southwood@xxxxxxxxx>

I decided to return to the first driver I touched. I found some more
things that could be cleaned up a little.
