From c75b8dc84fd28511224a4cd2bfa791bb56a06172 Mon Sep 17 00:00:00 2001 From: Irina Tirdea Date: Sat, 6 Dec 2014 00:18:08 +0200 Subject: [PATCH] iio: accel: kxcjk-1013: only set power state if CONFIG_PM is defined When CONFIG_PM is not defined and the driver tries to power off the device, kxcjk1013_set_power_state will call pm_runtime_put_autosuspend, which is not implemented (wil return -ENOSYS). Only call pm_runtime calls to change power state when CONFIG_PM is defined.
