[ 28/69] iwlwifi: disable WoWLAN if !CONFIG_PM_SLEEP

From: Ben Hutchings
Date: Sun Jun 17 2012 - 14:26:51 EST


3.2-stable review patch. If anyone has any objections, please let me know.

------------------

From: Johannes Berg <johannes.berg@xxxxxxxxx>

commit fcb6ff5e2cb83e1de10631f6621f45ca3401bf61 upstream.

If CONFIG_PM_SLEEP is disabled, then iwlwifi doesn't
support suspend/resume handlers and thus mac80211
(correctly) refuses advertising WoWLAN. Disable
WoWLAN in the driver in this case.
