Have you applied this patch:
Author: Ming Lei <tom.leim...@gmail.com>
Date: Fri Mar 27 21:50:00 2009 +0800
driver core: fix driver_match_device
This patch fixes a bug introduced in commit
49b420a13ff95b449947181190b08367348e3e1b.
If a instance of bus_type doesn't have .match method,
all .probe of drivers in the bus should be called, or else
the .probe have not a chance to be called.
