From 8890d05ff5f4bc0ba81f2d3d845cc95631c78cac Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Fri, 17 Oct 2014 07:40:14 +0530 Subject: [PATCH] ath9k: Clear NoA schedule properly When an active context transitions to inactive state, the NoA schedule needs to be removed for the context that has beaconing enabled. Not doing this will affect p2p clients. Signed-off-by: Sujith Manoharan Signed-off-by: John W.
