From 937d8fb4f80b17de1d7e541c850d215875558e81 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Mon, 20 Dec 2010 11:29:59 -0500 Subject: [PATCH] ath9k: fix aphy / wiphy idle mismatch commit afe68d0a8f5961652e26cea39d74e2cc820de841 upstream. ath9k supports its own set of virtual wiphys, and it uses the mac80211 idle notifications to know when a device needs to be idle or not. We recently changed ath9k to force idle on driver stop() and on resume but forgot to take into account ath9k's own virtual wiphy idle states. These are used internally by ath9k to check if the device's radio should be powered down on each idle call. Without this change its possible that the device could have been forced off but the virtual wiphy idle was left on. Cc: Paul Stewart Cc: Amod Bodas Signed-off-by: Luis R.
