[PATCH] i2c: Fallback to of_node of parent

[Florian Meier]

I have looked through all bus drivers and in most
cases they have a corresponding line that could be removed.

Although, this patch would break i2c-powermac, because it
relies on the fact that of_node stays NULL.

Any idea how to handle that?

Greetings,
Florian
