Subject: [PATCH v2 4/5] Staging: comedi: addi-data: tidy up timer register map defines in hwdrv_apci1564.c
This patch for fixes the register map defines for the timer registers such
that they are all the real offsets to each register, rather than a mix of
real offsets and adders to those offsets.
Signed-off-by: Chase Southwood <chase.southwood@...oo.com>

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