+  get_device(&int3472->sensor->dev);

I see no corresponding put_device(), am I missing something ? I'm also
not sure why this is needed.

The put is acpi_dev_put() in skl_int3472_discrete_remove(); there seems
to be no acpi_dev_get() for some reason. We use the sensor acpi_device
to get the clock frequency, and to fetch the sensor module string, so I
thought it ought to hold a reference on those grounds.

Shouldn't acpi_dev_get_dependent_dev() increase the reference count
then, instead of doing it manually here ?

That's what I expected as well.
We have plenty of acpi_dev_get_*() and they do increase the reference
counter one way or the other.
