Good suggestion.  I have posted a series with the title "Add automatic
bus number support for i2c busses with device tree".  It contains the
i2c-core patch as well as a patch removing similar code from the pxa
i2c driver.

Kukjin: please consider this patch abandoned and superseded by the new
i2c-core patch.  As Olof said, the patch for adding aliases for
exynos4 should still be fine to apply.


Thanks!
