From 4498863cad7befbbd14006e033ae84784a33ae53 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Wed, 20 Oct 2021 10:53:49 +0200 Subject: iio: st-sensors: Use dev_to_iio_dev() in sysfs callbacks Using `dev_get_drvdata()` in IIO sysfs callbacks to get a pointer to the IIO device is a relic from the very early days of IIO. The IIO core as well as most other drivers have switched over to using `dev_to_iio_dev()` instead. This driver is one of the last few drivers remaining that uses the outdated idiom, update it. This will allow to eventually update the IIO core to no longer set the drvdata for the IIO device and free it up for driver usage.
