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