Subject: [PATCH 2/4] iio: accel: kxcjk-1013: only set power state if CONFIG_PM is defined
Date: Sat,  6 Dec 2014 00:18:08 +0200	[thread overview]
Message-ID: <1417817890-10252-3-git-send-email-irina.tirdea@intel.com> (raw)
In-Reply-To: <1417817890-10252-1-git-send-email-irina.tirdea@intel.com>

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.
