[PATCH] Remove suspend() calls from shutdown path
This removes the calls to device_suspend() from the shutdown path that were added sometime during 2.6.13-rc*. They aren't working properly on a number of configs (I got reports from both ppc powerbook users and x86 users) causing the system to not shutdown anymore. I think it isn't the right approach at the moment anyway. We have already a shutdown() callback for the drivers that actually care about shutdown and the suspend() code isn't yet in a good enough shape to be so much generalized. Also, the semantics of suspend and shutdown are slightly different on a number of setups and the way this was patched in provides little way for drivers to cleanly differenciate. It should have been at least a different message. For 2.6.13, I think we should revert to 2.6.12 behaviour and have a working suspend back.
