Subject: iio: accel: kxcjk-1013: only set power state if CONFIG_PM is defined
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c75b8dc84fd28511224a4cd2bfa791bb56a06172;p=linux-beck.git

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.
