wl12xx_sdio: declare support for NL80211_WOW_TRIGGER_ANYTHING trigger
Eliad Peller [Fri, 13 May 2011 08:57:12 +0000 (11:57 +0300)]
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.
