[PATCH 2.4] I2C updates for 2.4.31-pre1 (3/3)

[Jean Delvare]

Fix an iteration bug in the handling of i2c client module parameters.
The "force" module parameter is a list of adapter, address pairs, not
triplets. The current code would only handle the first, fourth, seventh
etc. pairs properly. I guess that nobody ever needed more than one pair,
or the bug would have been noticed way earlier. This bug was originally
fixed by myself in Linux 2.6.
