Unlike for-next-acked-merged, the other branches aren't rebased and therefore have merge conflicts with 3.3 material; that's intentional.

Not a 3.3-based one, so I recommend you to just merge Marek's branch directly.
I'll soon create a full-fledged 3.3 branch though, so you may want to wait a bit until I get to it.

If your driver boots the remote core on its ->probe() handler, then yes, you need to unbind and bind the device.
One way is to unload and load the driver, but you can also use the bind/unbind sysfs files of your driver (echo -n device-name > /sys/..../{un}bind).
