Re: [BK PATCH] i2c driver fixes for 2.6.0-test2

[Mark M. Hoffman]

This is a resend of a patch to the i2c-nforce2.c I2C bus driver.
The start of the relevant thread was here:
http://archives.andrew.net.au/lm-sensors/msg03820.html

[comment]
This patch restores a line that was wrongly removed.  There are also some
trivial cleanups.  It applies & compiles vs. 2.6.0-test3.  It's untested
(no hardware here).
