Well.
This commit increases the size of struct device quite a bit and both of the drivers above create a "state" object on the stack that contains struct device among other things.
I think they should allocate these objects using kmalloc() and I don't know what I can do about this, really. Maybe except for modifying the drivers to use kmalloc().
