This is wrong, for the usual reason that instance_init cannot touch
globals.  The right thing to do here would be to add a chardev property
to the device as in the FIXME; at this point, it is obvious that the
rest must be in a init or realize callback, because the properties are
not available in init.

Same for patch 4.
