Based on the warning-fix I submitted yesterday, this probably produces
a warning if CONFIG_PM is set but not CONFIG_PM_SLEEP. My patch was
for an ethernet driver, but iwlwifi and ath5k appear to follow the
same pattern using CONFIG_PM_SLEEP instead of the above.
See: http://www.spinics.net/lists/netdev/msg184717.html for the patch
and http://www.spinics.net/lists/netdev/msg184715.html for the
discussion.
