Maybe it shouldn't use this pointer directly then?


aic32x4_probe() has these lines

        aic32x4->type = (uintptr_t)dev_get_drvdata(dev);
        dev_set_drvdata(dev, aic32x4);

Dragging data like this makes a little sense to me. What you should do is to
have a precursor patch that adds a third parameter to ->probe().

Also it makes sense to all your improvements for -i2c.c do similar to all
-spi.c cases where it applies.
