Nikolaus,

I am getting some notices sent to me when I apply your series.  It
works, but I want to clean up the notice.  Can you suggest what might
cause this:

     debugfs: Directory 'cpu0-cpu0' with parent
'48070000.i2c:twl@48:regulator-vdd1-VDD1' already present!

It wasn't present before your series.  It's not a big deal, but I'd
like to quiet down the messages if I can.
Thanks.

adam
