From 056508dcb6890586745aa937e779f00fde05531b Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 30 Jul 2009 21:43:55 +0200 Subject: [PATCH] mac80211: fix powersave Some of the recent MLME rework I did broke powersave because the ps_sdata isn't assigned at the right time, and the work item wasn't removed from the list before calling ieee80211_recalc_ps(). To be more specific, this broke the case where you'd enabled PS before associating, either automatically or with iwconfig. Signed-off-by: Johannes Berg Signed-off-by: John W.
