From 661d25815ea533d06c7535ddd1c4810fa7ab9e22 Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Fri, 30 Jan 2015 19:05:26 +0530 Subject: [PATCH] ath9k: Fix wow init/deinit Registering the card as a wakeup source needs to be done once, during initialization. When the WOW configuration changes, the card's status as wakeup source needs to be changed too and this is done via the set_wakeup() callback. Also, make sure the device is removed properly using ath9k_deinit_wow().
