Hello linux-kernel,

We here at Handhelds.org upgrading our drivers to 2.6.18 and I just
caught a case of find_bus() being undefined during link.

I assume you are referring to the ipaq h2200 battery driver that uses
bus = find_bus("w1");
to "find" the one wire bus?

I think the solution would be to use w1_bus_type instead, but for that
it would have to be exported.
