Message-Id: <200701231720.36370.mb@bu3sch.de>

Subject: [PATCH review] b44: Port to ssb subsystem
This patch ports b44 to the new SSB subsystem and makes
it possible to turn off PCI related stuff.
This patch is against my tree, where I have implemented the
ssb subsystem.
If you're all OK with this patch, I'd like apply it to my tree.
I think that's best. Although it's not wireless-related, it's
much easier to maintain this way.
This patch is tested on a b4401b0
This patch also makes it possible to run the driver on b47xx devices.
