SubjectRe: [PATCH] slimbus: Linux driver framework for SLIMbus.
The patch below fixes an bug where devices that have not be matched
to a driver will result in a segv when the bus is shutdown.

I am not sure what the policy on patches-on-patches is, it just
doesn't seem workable. So I this will be the first and last. Instead I
am maintaing a git repository that tracks Linus's tree:

git://git.plastictigers.com/slimbus.git

or it can be browsed via the web:

http://git.plastictigers.com/

Currently there are 3 branches:

slimbus-rfc-patch : the original rfc patch (for reference)
slimbus-patch : the current patch (as posted by Sagar)
slimbus-patch-fixes : slimbus-patch + fixes (like the one below)

There will likely be a couple of new branches in the future.

If anyone has a suggestion on a better way of doing this I am all
ears.
