From 0ebbdd734f2509bae17f4340fc4fd07c530dbc59 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Wed, 23 Dec 2009 20:03:28 -0500 Subject: [PATCH] ath9k: wake hardware for interface IBSS/AP/Mesh removal commit 5f70a88f631c3480107853cae12925185eb4c598 upstream. When we remove a IBSS/AP/Mesh interface we stop DMA but to do this we should ensure hardware is on. Awaken the device prior to these calls. This should ensure DMA is stopped upon suspend and plain device removal. Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.
