From 5363c6c17b1014f696bf0b2984af4b694062ce8f Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Mon, 23 Aug 2021 14:22:02 +0300 Subject: iio: st_sensors: remove st_sensors_power_disable() function This change converts the st_sensors_power_enable() function to use devm_add_action_or_reset() handlers to register regulator_disable hooks for when the drivers get unloaded. The parent device of the IIO device object is used. This is based on the assumption that all other devm_ calls in the ST sensors use this reference. This makes the st_sensors_power_disable() un-needed. Removing this also changes unload order a bit, as all ST drivers would call st_sensors_power_disable() first and iio_device_unregister() after that.
