[PATCH v2 2/3] iio: accel: BMC150: fix issues when CONFIG_PM_RUNTIME is not set

From: Laurentiu Palcu
Date: Fri Aug 29 2014 - 04:38:24 EST


When CONFIG_PM_RUNTIME is not set, the following issues are seen:
* warning message at compilation time:
warning: 'bmc150_accel_get_startup_times' defined but not used [-Wunused-function]
* bmc150_accel_set_power_state() will always fail and reading the
accelerometer data is impossible;

This commit fixes these.
