[PATCH v4 13/36] iio: position: hid-sensor-custom-intel-hinge: use common device for devres

[Sanjay Chitroda]

From: Sanjay Chitroda <sanjayembeddedse@xxxxxxxxx>

kmemdup() is used for memory that is logically tied to the HID
platform device, even though the driver binds into the IIO framework.

Using &indio_dev->dev for devres allocations works functionally, but it
results in two separate devres ownership trees—one for the HID
platform device (pdev) and another for the IIO device (indio_dev).

The devres framework is intended to have a single, well-defined parent
device. Since the memory originates from HID sensor probing and is not
IIO-specific, &pdev->dev is the correct and logical owner.

Switch to using the platform device for devm_kmemdup() so that all
resources are released deterministically and consistently.
