From b31b05cf629574d47b324bb52128ed1b199faccd Mon Sep 17 00:00:00 2001 From: Laurentiu Palcu Date: Fri, 29 Aug 2014 09:38:00 +0100 Subject: [PATCH] iio: accel: BMC150: fix issues when CONFIG_PM_RUNTIME is not set 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 occurs because of the call to pm_runtime_put_autosuspend calls __pm_runtime_suspend which returns -ENOSYS. This commit fixes these.
