From c94f5806cd0be4c7d4dabb89d1ae1088ed4332e7 Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Fri, 7 Apr 2017 17:16:34 -0700 Subject: [PATCH] iio: hid-sensor: Fix unbalanced pm_runtime_enable error When a hid sensor module is removed and modprobed again we see error for unbalanced pm_runtime. This issue is caused by not deactivating runtime PM on removal. So on modprobe again when activated again, this will print this error.
