[PATCH] i2c/pnx: Really fix start/stop issue

[Wolfram Sang <w.sang-bIcnvbaLZ9MEGnE8C9+IrQ@public.gmane.org>]

The issue was truly solved by the second patch in this thread:

http://thread.gmane.org/gmane.linux.drivers.i2c/5436

Accidently, the first one was picked up. So, this patch adds the
remaining diff (and an additional newline).

Jean, can you pick this up, so it will be correct in 2.6.34?
