From ec25bb6e84a090da9c5c397c8af962dcb2e1c664 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 3 Jun 2022 12:59:59 +0300 Subject: [PATCH] iio: adc: meson_saradc: Don't attach managed resource to IIO device object 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.
