Hi,

Ick.  struct device should _never_ be on the stack, why would this code
want to do such a thing?

When you are doing a thing it does not necessarily you know that you're doing it.

It appears that the state object is a dummy being used to detect and
twiddle some identical chips on the i2c bus.  The functions called only
use the "i2c_adapter" and "cfg" member of the dummy state object, but
those functions want that state object as an input argument.

<obvious>
The simplest fix is dynamic allocation of the dummy state object with
kmalloc() and then to free it before exiting the function.
</obvious>

Even more obvious: Fix the function with simpler code to do the same thing.

I will try to fetch some time from somewhere to work on it.
