[PATCH v3 1/6] iio: adc: meson_saradc: Don't attach managed resource to IIO device object

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

It feels wrong and actually inconsistent to attach managed resources
to the IIO device object, which is child of the physical device object.
The rest of the ->probe() calls do that against physical device.

Resolve this by reassigning managed resources to the physical device object.

Fixes: 3adbf3427330 ("iio: adc: add a driver for the SAR ADC found in Amlogic Meson SoCs")
