Linville" Subject: [ 16/42] iwlwifi: disable WoWLAN if !CONFIG_PM_SLEEP In-Reply-To: <20120614235636.GA5275@kroah.com> Sender: linux-kernel-owner@vger.kernel.org List-ID: 3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Johannes Berg 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.
