+ 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.
Okedokey, I'll move the get() to that function and drop it from here.
