Follow-ups

--- Barry Song 2010-06-03 05:47:58

The board has corrupted. I can't pull up the #CLATCH to high level with pull-up

res. The ad1939 will be in standalone mode and can't be controlled by cpu. but

ad1939 has same register layout and driver with ad1938. since it has worked

before, close it.

--- Sonic Zhang 2010-06-03 05:57:09

Because this driver is tested against ad1938 now without problem. Close this bug

against 1939.
