From a95a0b4e471a6d8860f40c6ac8f1cad9dde3189a Mon Sep 17 00:00:00 2001 From: Sean Nyekjaer sean@geanix.com Date: Mon, 1 Sep 2025 09:49:14 +0200 Subject: iio: imu: inv_icm42600: Drop redundant pm_runtime reinitialization in resume
Remove unnecessary calls to pm_runtime_disable(), pm_runtime_set_active(), and pm_runtime_enable() from the resume path. These operations are not required here and can interfere with proper pm_runtime state handling, especially when resuming from a pm_runtime suspended state.
