Revision 38a529b5d42e4cfc5ac94844e61335a00eb2d320 authored by Mika Westerberg on 16 January 2014, 12:39:39 UTC, committed by David S. Miller on 16 January 2014, 23:36:26 UTC
Commit 7509963c703b (e1000e: Fix a compile flag mis-match for suspend/resume) moved suspend and resume hooks to be available when CONFIG_PM is set. However, it can be set even if CONFIG_PM_SLEEP is not set causing following warnings to be emitted: drivers/net/ethernet/intel/e1000e/netdev.c:6178:12: warning: ‘e1000_suspend’ defined but not used [-Wunused-function] drivers/net/ethernet/intel/e1000e/netdev.c:6185:12: warning: ‘e1000_resume’ defined but not used [-Wunused-function] To fix this make the hooks to be available only when CONFIG_PM_SLEEP is set and remove CONFIG_PM wrapping from driver ops because this is already handled by SET_SYSTEM_SLEEP_PM_OPS() and SET_RUNTIME_PM_OPS().
