Subject: [PATCH v2 5/6] wl12xx_sdio: declare support for NL80211_WOW_TRIGGER_ANYTHING trigger
Date: Fri, 13 May 2011 11:57:12 +0300 [thread overview]
Message-ID: <1305277033-6662-6-git-send-email-eliad@wizery.com> (raw)
In-Reply-To: <1305277033-6662-1-git-send-email-eliad@wizery.com>
Since wowlan requires the ability to stay awake while the host
is suspended, declare support for NL80211_WOW_TRIGGER_ANYTHING
if the MMC_PM_KEEP_POWER capability is being supported.
