Subject: [PATCH] iio:proximity:sx_common: Fix device property parsing on DT systems
Date: Thu, 31 Mar 2022 14:04:25 -0700	[thread overview]
Message-ID: <20220331210425.3908278-1-swboyd@chromium.org> (raw)

After commit 7a3605bef878 ("iio: sx9310: Support ACPI property") we
started using the 'indio_dev->dev' to extract device properties for
various register settings in sx9310_get_default_reg(). This broke DT
based systems because dev_fwnode() used in the device_property*() APIs
can't find an 'of_node'. That's because the 'indio_dev->dev.of_node'
pointer isn't set until iio_device_register() is called. Set the pointer
earlier, next to where the ACPI companion is set, so that the device
property APIs work on DT systems.
